        a predefined entity (as happens for array index types), the line is set
        to 0.
        Add support for parsing multiple array index types info, or
        multiple inherited interfaces info. This information cannot be stored
        in Xref_Entity_Record, which only supports a single instance of Tref_*,
        and is therefore stored in the list of references instead. It has a

        Dismukes). After this patch there is no need to perform any
        additional management on these nodes in Expand_Interface_Actuals.

        * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
        that handles use of 'Access and 'Unchecked_Access applied to

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

        compilation mode and whether the designated type is limited.

         indirection added to the HT_Link component of the TSD. This is required
         to statically allocate the TSD.

        * a-tags.ads: 
        Minor reordering of the declarations in the private part. Required to
        add a level of indirection to the contents of the TSD component HT_Link.
        This is required to statically allocate the TSD.

        * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
        Is_Statically_Allocated set from constant objects.
        Do not make exported constants created by the compiler volatile.
        (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
        as read-only.

        * trans.c (Identifier_to_gnu): For constants, unshare initializers
        before returning them.

        * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
        public part of the package.
        (Make_DT): Move HT_Link component out of the TSD record. For this
        purpose Make_DT now declares a separate object that stores the
        HT_Link value, and initializes the TSD component with the address
        of this new object. The addition of this level of indirection is
        required to statically allocate the TSD because the TSD cannot
        have variable components.
        (Expand_Interface_Conversion): Improve the expanded code.
        (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.

        * sem_disp.adb (Check_Dispatching_Operation): In case of a body
        declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
        if we are building static dispatch tables then we must not generate
        extra code to register the primitive because the dispatch table will
        be built at the end of the library package; otherwise we notify that
        we cannot build the static dispatch table.

        of errors in the documentation in this regard).

        * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.

        * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any

        Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
        the case where processing continues.
        (Expand_Call): If the call is generated from a thunk body then we
        propagate the extra actuals associated with the accessibility
        level of the access type actuals.

        * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
        of each extra formal of a protected operation to reference the

        * sem_ch7.adb (Analyze_Package_Specification): Add check for
        preelaborable initialization of a full view in entity loop.
        (Uninstall_Declarations): If entity is a use-visible compilation unit,
        its child units are use-visible only if they are visible child units.

        * sem_util.adb (Is_Preelaborable_Expression): New function to determine
        whether an expression can be used within a type declaration that
        requires preelaborable init.
        (Check_Components): Replace inline code that does partial checking for
        preelaborable default expressions with call to
        Is_Preelaborable_Expression.
        (Has_Preelaborable_Initialization): In the case of a generic actual
        subtype, (that is, Is_Generic_Actual is True), return the result of
        applying Has_Preelaborable_Initialization to the generic actual's base
        type.

2007-09-26  Hristian Kirtchev  <kirtchev@adacore.com>

        (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
        weekday on which January 1 falls of Year - 1 and Year + 1. This function
        avoids calling Time_Of and Split, thus making it more efficent.
        (Week_In_Year): Reimplemented in oder to follow ISO 8601.

        * g-calend.ads (Week_In_Year): Change comment to reflect new
        implementation.

2007-09-26  Emmanuel Briot  <briot@adacore.com>

        * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
        Command_Line): New types
        (Define_Alias, Define_Prefix, Free): New subprograms. These provide
        support for defining how switches can be grouped on a command line (as
        is the case for -gnatw... for GNAT), and how simple switches can be
        used as aliases for more complex switches (-gnatwa is same as
        -gnatwbcef...)
        (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
        (Start, Current_*): New subprograms
        Added support for parsing an array of strings in addition to the real
        command line.
        (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
         be moved from the body to the private part of the spec.
        (*): All subprograms now have an extra parameter with default value to
        specify which parser should be used. For backward compatibility, it
        defaults to parsing the command line of the application. They were also
        modified to properly handle cases where each of the argument does not
        start at index 1 (which is always true for Ada.Command_Line, but not
        when processing any Argument_List).
        (Free): New subprogram
        (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
        Argument): New subprograms
        (Switch_Parameter_Type): New enum, which clarifies the code. The extra
        special characters like ':', '=',... are now handled in a single place,
        which makes the code more extensible eventually.
        (Getopt, Full_Switch): When the switch was returned as part of the
        special character '*', make sure it is prepended by the switch character
        ('-' in general), so that the application knows whether "foo" or "-foo"
        was specified on the command line.

2007-09-26  Florian Villoing  <villoing@adacore.com>

        * g-dirope.adb (Remove_Dir): In case we are removing directories
        recursively, make sure that if an exception is raised during the
        processing, the current working directory is reset to its initial
        value before propagating the exception.

2007-09-26  Vincent Celier  <celier@adacore.com>

        * gnatbind.adb: If there are several ALI files specified and there is
        a main program to bind, the first ALI is expected to contain the main
        subprogram and the names of the binder generated files will be derived
        from the first ALI file name.
        (Gnatbind): Fix insertion character in invocation of Error_Msg

2007-09-26  Vincent Celier  <celier@adacore.com>

        * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
        process configuration attributes: this is done in Prj.Nmsc.Check.
        (Recursive_Process): Make a full copy of packages inherited from project
        being extended, instead of a shallow copy.
        (Process_Project_Tree_Phase_1): New procedure

        (Process): Implementation now uses the two new procedures

        * prj-util.adb (Executable_Of): Get the suffix and the default suffix
        from the project config, not the tree config that no longer exists.

2007-09-10  Gary Dismukes  <dismukes@adacore.com>
            Thomas Quinot  <quinot@adacore.com>

        * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
        create an abstract subprogram in the case of 'Input. For 'Output we now
        create a real spec/body when the type is abstract, since it can
        potentially be called.
        (Predefined_Primitive_Bodies): Now allow the creation of a predefined
        body for 'Output when the type is abstract (only the creation of the
        body for 'Input is excluded when the type is abstract).
        (Stream_Operation_OK): Add an additional condition in the return
        statement, so that False will be returned for TTS_Stream_Input if the
        associated tagged type is an abstract extension. Add comments for
        return statement.
        (Expand_N_Object_Declaration): For the case of a shared passive
        variable, insert init proc call only after the shared variable
        procedures have been processed, because the IP call needs to undergo
        shared passive variable reference expansion, which requires these
        procedures to be available (and elaborated).

        type, retrieve its value from the aggregate itself, where it must have
        been supplied.

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

        * cstand.adb (Create_Standard): Create an entity for a zero-sized type
        associated with Standard_Debug_Renaming_Type, to be used as the type of
        the special variables whose names provide debugger encodings for
        renaming declarations.

        * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
        (Set_Debug_Renaming_Link): Change to set Node25.
        (Write_Field13_Name): Remove case for E_Enumeration_Literal.
        (Write_Field25_Name): Add case for E_Variable to output

        Standard_Debug_Renaming_Type whose name encodes both the renamed object
        and the entity of the renaming declaration.
        (Qualify_Entity_Name): Add the delayed qualification of the entity name
        part of the name of a variable that has a Debug_Renaming_Link.

        * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
        special type to be associated with variables that provide debugger

        * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
        ancestor part given by an aggregate to test for an unchecked conversion,
        since this can occur in some cases when the ancestor part is a function
        call, and we don't want to fall into the recursive call to this
        procedure in that case.

        * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
        stream attributes on limited types to account for user-specified
        attributes as well as whether Input (resp. Output) becomes available
        due to Read (resp. Write) being available for the type. Change Boolean
        variable to the more accurate name
        Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
        double-"not" predicate at beginning of return statement to more
        understandable form.

        * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
        return has an associated N_Handled_Sequence_Of_Statements, then wrap it
        in a block statement and use that as the first statement of the
        expanded return rather than incorrectly using the handled sequence as
        the first statement.

        * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
        operation, generate an explicit freeze node for it rather than
        generating extra formals, to ensure that gigi has the proper order of
        elaboration for anonymous subtypes in the signature of the subprograms.
        (Build_In_Place_Formal): Move assertion to beginning of loop.
        (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
        applied to a function call (occurs for some cases of 'Input).
        (Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion
        applied to a function call (occurs for some cases of 'Input).

        * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
        2005, generate an extended return statement enclosing the result object
        and 'Read call.

        * freeze.adb (Freeze_Record_Type): Extend the current management of
        components that are access type with an allocator as default value: add
        missing support to the use of qualified expressions of the
        allocator (which also cause freezing of the designated type!)
        (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
        dispatching operation, since extra formals may be needed by calls to
        build-in-place functions (such as stream 'Input).

        * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
        formals for 'Constrained and accessibility level in the case of a
        predefined dispatching operation.

        * exp_util.adb (Insert_Actions): A protected body is a valid insertion
        point, no need to find the parent node.

2007-08-16  Javier Miranda  <miranda@adacore.com>

        * exp_attr.adb (Attribute_Priority): Add missing support for entries
        and entry barriers.

2007-08-16  Javier Miranda  <miranda@adacore.com>

        * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
        is not really required and can introduce regression with the debugger.
        The original problem is fixed with the patch written for checks.adb.

2007-08-16  Thomas Quinot  <quinot@adacore.com>

        * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

        Including_Non_Switch set to False.

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

2007-08-16  Nicolas Roche  <roche@adacore.com>

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

        exception case

2007-08-16  Ed Schonberg  <schonberg@adacore.com>

        * sem_disp.adb (Check_Dispatching_Operation): If the operation
        implements an operation inherited from a progenitor interface, verify
        that they are subtype-conformant.

            Bob Duff  <duff@adacore.com>
            Nicolas Setton  <setton@adacore.com>

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

        * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
        the parser has folded a long sequence of concatenations of string
        literals.

        * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
        and "JMP_BUF" variables as artificial.
        (N_String_Literal): Do not use alloca for very long string literals. Use

        (Difference): Account for possible rounding of the resulting difference

2007-08-14  Robert Dewar  <dewar@adacore.com>

        * uintp.adb, a-ztedit.adb, s-wchcon.adb, xnmake.adb, s-wchcon.adb,

            Ed Schonberg  <schonberg@adacore.com>

        * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads: 
        Suppress unmodified in-out parameter warning in some cases
        This patch is a also fairly significant change to the way suppressible
        checks are handled.

        * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
        needed for access to concurrent record types generated by the expander.
        (Generate_Range_Check): When generating a temporary to capture the
        value of a conversion that requires a range check, set the type of the
        temporary before rewriting the node, so that the type is always
        properly placed for back-end use.
        (Apply_Float_Conversion_Check): Handle case where the conversion is
        truncating.
        (Get_Discriminal): Code reformatting. Climb the scope stack looking
        for a protected type in order to examine its discriminants.

        (Get_Allocator_Final_List): For the case of an anonymous access type
        that has a specified Associated_Final_Chain, do not go up to the
        enclosing scope.
        (Expand_N_Type_Conversion): Test for the case of renamings of access
        parameters when deciding whether to apply a run-time accessibility
        check.
        (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
        aggregate code before allocator, and ahead of declaration for
        temporary, to prevent access before elaboration when the allocator is
        an actual for an access parameter.
        (Expand_N_Type_Conversion): On an access type conversion involving an
        access parameter, do not apply an accessibility check when the
        operand's original node was an attribute other than 'Access. We now
        create access conversions for the expansion of 'Unchecked_Access and
        'Unrestricted_Access in certain cases and clearly accessibility should
        not be checked for those.

        * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
        includes a type conversion of a packed component that has been expanded,
        recover the original expression for the object, and use this expression
        in the post-call assignment statement, so that the assignment is made
        to the object and not to a back-end temporary.
        (Freeze_Subprogram): In case of primitives of tagged types not defined
        at the library level force generation of code to register the primitive
        in the dispatch table. In addition some code reorganization has been
        done to leave the implementation clear.
        (Expand_Call): When expanding an inherited implicit conversion,
        preserve the type of the inherited function after the intrinsic
        operation has been expanded.

        * exp_ch2.ads, exp_ch2.adb
        (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
        of an entry formal appearing in an assignment statement does not assign
        to the formal.
        (Expand_Current_Value): Instead of calling a routine to determine
        whether the prefix of an attribute reference should be optimized or
        not, prevent the optimization of such prefixes all together.

        * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
        component whose prefix is known to be of an access type is an implicit
        dereference and does not assign to the prefix.

            Robert Dewar  <dewar@adacore.com>

        * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and

        new itype.
        Add comments and correct harmless error in Build_NCT_Hash_Tables
        (Array_Aggr_Subtype): Associate each itype created for an index type to
        the corresponding range construct, and not to the aggregate itself. to
        maintain a one-to-one correspondence between itype and its associated
        node, to prevent errors when complex expression is copied.
        Fix mishandling of multiple levels of parens

        * sem_aggr.adb: Create a limited view of an incomplete type, to make
        treatment of limited views uniform for all visible declarations in a
        limited_withed package.
        (New_Copy_Tree): If hash table is being used and itype is visited,
        make an entry into table to link associated node and new itype.
        (Resolve_Record_Aggregate): Do not add an others box association for a
        discriminated record component that has only discriminants, when there
        is a box association for the component itself.

        * par-ch4.adb: Fix mishandling of multiple levels of parens

        generation of a freezing node to ensure proper management of null
        excluding access types in the backend.
        (Create_Extra_Formals): Test base type of the formal when checking for
        the need to add an extra accessibility-level formal. Pass the entity E
        on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
        originally being done in a couple of cases), to ensure that the
        Extra_Formals list gets set on the entity E when the first entity is
        added.
        (Conforming_Types): Add missing calls to Base_Type to the code that
        handles anonymous access types. This is required to handle the
        general case because Process_Formals builds internal subtype entities
        to handle null-excluding access types.
        (Make_Controlling_Function_Wrappers): Create wrappers for constructor
        functions that need it, even when not marked Requires_Overriding.
        Improve warnings for in out parameters

        Warn on return from procedure with unset out parameter
        Ensure consistent use of # in error messages

        (Analyze_Function_Return): Move call to Apply_Constraint_Check before
        the implicit conversion of the expression done for anonymous access
        types. This is required to generate the code of the null excluding
        check (if required).

        * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
        A formal parameter is never publicly referenceable outside of its body.
        (Check_References): For an unreferenced formal parameter in an accept
        statement, use the same warning circuitry as for subprogram formal
        parameters.
        (Warn_On_Unreferenced_Entity): New subprogram, taken from
        Output_Unreferenced_Messages, containing the part of that routine that
        is now reused for entry formals as described above.
        (Goto_Spec_Entity): New function
        (Check_References): Do not give IN OUT warning for dispatching operation
        Improve warnings for in out parameters

        three forms of access attributes, using common code now for all three
        cases. Add a test for the case of applying an access attribute to
        an explicit dereference when the context is an access-to-interface
        type. In that case we need to apply the conversion to the prefix
        of the explicit dereference rather than the prefix of the attribute.
        (Attribute_Version, UET_Address): Set entity as internal to ensure
        proper dg output of implicit importation.
        (Expand_Access_To_Type): Removed.
        (Expand_N_Attribute_Reference): Merge the code from the three cases
        of access attributes, since the processing is largely identical for
        these cases. The substantive fix here is to process the case of a
        type name prefix (current instance case) before handling the case
        of interface prefixes.

        initialization of secondary tags.
        (Is_Variable_Size_Record): New implementation.
        (Expand_N_Object_Declaration): Suppress call to init proc if there is a
        Suppress_Initialization pragma for a derived type.
        (Is_Variable_Size_Record): New subprogram.
        (Build_Offset_To_Top_Functions): New implementation that simplifies the

        (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
        first formal of the thunk is always associated with the controlling
        type. In addition perform the following code cleanup: remove formal
        Thunk_Alias which is no longer required, cleanup evaluation of the
        the controlling type, and update the documentation.
        Replace occurrence of Default_Prim_Op_Count by

        construction of statically allocated dispatch tables.
        (Make_DT): In case of library-level tagged types export the declaration

        declaration of the primary tag that will be declared later by Make_DT.
        (Expand_Interface_Conversion): In case of access types to interfaces

            Javier Miranda  <miranda@adacore.com>

        * exp_util.ads, exp_util.adb: 
        This patch replaces a number of occurrences of explicit tests for N_Null
        with calls to Known_Null. This improves tracking of null values, since
        Known_Null also catches null constants, and variables currently known to
        be null, so we get better tracking.
        (Ensure_Defined): create an itype reference only in the scope of the
        itype.
        (Side_Effect_Free): A selected component of an access type that
        denotes a component with a rep clause must be treated as not
        side-effect free, because if it is part of a linked structure its
        value may be affected by a renaming.
        (Expand_Subtype_From_Expr): For limited objects initialized with build
        in place function calls, do nothing; otherwise we prematurely introduce
        an N_Reference node in the expression initializing the object, which
        breaks the circuitry that detects and adds the additional arguments to
        the called function. Bug found working in the new patch for statically
        allocated dispatch tables.
        (Is_Library_Level_Tagged_Type): New subprogram.
        (Remove_Side_Effects): If the expression of an elementary type is an
        operator treat as a function call.
        (Make_Literal_Range): If the index type of the array is not integer, use
        attributes properly to compute the constraint on the resulting aggregate
        which is a string.

        * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
        class-wide type whose base type is an incomplete private type, leave
        class-wide type unfrozen so that freeze nodes can be generated
        properly at a later point.
        (Freeze_Entity, array case): Handle case of pragma Pack and component
        size attributre clause for same array.

        (Collect_Previous_Instances): new procedure within of

        takes progenitor types into account.
        (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by

        (Complete_Object_Operation): If actual has an access type and
        controlling formal is not an in_parameter, reject the actual if it is
        an access_to_constant type.
        (Try_Primitive_Operation): If the type of the prefix is a formal tagged
        type, the candidate operations are found in the scope of declaration of
        the type, because the type has no primitive subprograms.
        (Analyze_Selected_Component): If prefix is class-wide, and root type is
        a private extension, only examine visible components before trying to
        analyze as a prefixed call.

        formal At_Any_Place indicating, when True, that we want to test for
        availability of the stream attribute at any place (as opposed to the

        Take into account the Ada2005 pragma Has_Preelaborable_Initialization
        when checking the legality of an extension aggregate in a preelaborable
        package. Treat the literal null as a valid default expression in a
        component declaration for a type with preelaborable initialization.
        A limited interface is a legal progenitor for the designated type of a
        remote access to class-wide type.

        bounds of the slice to construct the required constraint checks.
        Improve NOT NULL error messages
        (Apply_Constraint_Check): If the context is a null-excluding access
        type, diagnose properly the literal null.

        * clean.adb (Clean_Archive): Use untouched casing for the archive name
        and the corresponding .deps file.
        (Clean_Interface_Copy_Directory): Use untouched casing for the library
        src directory. Minor code-clean-up. Use untouched casing for files
        read into the library src dir.
        (Clean_Library_Directory): Idem.
        (Parse_Cmd_Line): Accept new switch -aP

            Arnaud Charlet  <charlet@adacore.com>

        * einfo.ads, einfo.adb (Available_View): New synthesized attribute
        applicable to types that have the With_Type flag set. Returns the
        non-limited view of the type, if available, otherwise the type itself.
        For class-wide types, there is no direct link in the tree, so we have
        to retrieve the class-wide type of the non-limited view of the Etype.
        New attributes Static_Initialization and Static_Elaboration_Desired.
        Remove the pragma Thread_Body, and the associated flag
        Is_Thread_Body in entities, and all related code.
        (Suppress_Value_Tracking_On_Call): New flag
        E_Exception has Esize and Alignment fields
        (Universal_Aliasing): New function.
        (Set_Universal_Aliasing): New procedure.
        (Write_Entity_Flags): Deal with Universal_Aliasing flag.
        (Check_Nested_Access): New procedure.
        (Has_Up_Level_Access, Set_Has_Up_Level_Access): New procedures.
        (Find_Direct_Name, Note_Possible_Modification): Use Check_Nested_Access.
        (Related_Interface): New attribute. Present in dispatch table pointer
        components of records. Set to point to the entity of the corresponding
        interface type.
        (Is_By_Reference_Type): Recurse on the full view of an incomplete type.
        (Original_Access_Type): Remove, not needed.
        (Root_Type): Handle properly subtypes of class-wide-types.
        Update comments.

        * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
        class-wide types visible through limited-with clauses.
        (Try_Primitive_Operation): When examining all primitive operations of a
        tagged type, do not consider subprograms labeled as hidden unless they
        belong to a private generic type with a tagged parent.
        (Try_Object_Operation): Extensive rewriting, to handle properly various
        overloading cases, when several ancestors may have class-wide operations
        that are possible candidates, and when the overloaded functions return
        array types and have defaulted parameters so that the call may be
        interpreted as an indexing.
        (Analyze_Allocator): Remove Mark_Allocator and its invocation.
        (Process_Function_Call): use Next, rather than Next_Actual, to analyze
        successive actuals before analyzing the call itself.
        (Try_Primitive_Operation): A primitive operation is compatible with the
        prefix if the prefix has a synchronized type and the type of the formal
        is its corresponding record, as can be the case when the primitive
        operation is declared outside of the body of the type.
        (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
        perform homonym traversal, looking for class-wide operation matches
        (formerly done in statements of Try_Class_Wide_Operation). Matches on
        access parameters are now restricted to anonymous access types.
        (Mark_Allocator): An allocator with a discriminant association parent is
        a coextension.
        (Try_One_Prefix_Interpretation): If the type of the object is
        incomplete, as can be happen when it is a limited view obtained through
        a limited_with_clause, the selected component is not part of a prefixed
        call.
        (Complete_Object_Operation): Diagnose properly an object that is not
        aliased when the corresponding controlling formal is an access
        parameter.
        (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
        ambiguous calls in prefixed notation, where two primitives differ only
        in that the controlling argument of one is an access parameter.

        * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
        whether a function that returns an unconstrained type can be inlined.
        (Process_Formals): Diagnose properly the illegal use of an incomplete
        type in the profile of an access_to_subprogram declaration.
        (Check_Synchronized_Overriding): Nothing check for concurrent types, the
        operations are attached to the corresponding record.
        (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
        When processing a primitive of a concurrent type which implements an
        interface change the type of all controlling formals to that of the
        corresponding record type.
        (Check_Synchronized_Overriding): Relax the conditional logic when trying
        to determine the tagged type to which a primitive belongs.
        (Check_Conventions): Capture condition to ignore a primitive operation
        (which is shared between the loop in Check_Conventions and the one in
        Check_Convention) in a new local function Skip_Check.
        (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
        confusion with Check_Conventions' own Prim_Op local variable.
        (Create_Extra_Formals): Test for a tagged result type rather than a
        controlling result when determining whether to add a BIP_Alloc_Form
        formal and a BIP_Final_List formal to the function.
        (Check_Conformance); For parameters that are anonymous access types,
        subtype conformance requires that the not null and the constant
        indicators must match
        (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
        to retrieve the appropriate type when processing a concurrent type
        declared within a generic. Minor comment reformatting. Change invocation
        of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
        mitive.
        (Analyze_Subprogram_Body): If the return type of a function is an
        anonymous access to the limited view of a class-wide type, and the
        non-limited view of the type is available, update the type of the
        function so that code can be generated.
        (Process_Formals): In case of access-subtype itype whose designated
        type is also an itype (situation that happens now with access to
        subprograms) we mark the access-type itype with the Has_Delayed_Freeze
        attribute to avoid backend problems.
        (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
        init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
        anonymous types' designated types are same before testing
        Subtypes_Statically_Match.
        (Create_Extra_Formals): Test for a named access parameter that is a
        controlling formal as an additional condition for adding an
        accessibility level formal. This can occur in the subp type created for
        dispatching calls in Expand_Dispatching_Call, and allows calling
        Create_Extra_Formals from that procedure rather than special-casing the
        extra formals there.
        (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
        when the function has a controlling result.
        (Check_Returns): Add much more knowledge of the optimization of local
        raise statements to gotos, to retain proper warnings in this case.
        (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
        nodes when looking for last statement.

        * sem_type.ads, sem_type.adb (Specific_Type): Add support for
        class-wide types visible through limited with clauses.
        (Add_One_Interp): If the operands are anonymous access types, the
        predefined operator on universal_access is immediately visibles
        (Find_Unique_Type): Handle anonymous access to subprogram types just as
        other anonymous access types.
        (Disambiguate): Take into account CIL convention.
        (Interface_Present_In_Ancestor): Add support for class-wide interfaces.

2007-06-06  Robert Dewar  <dewar@adacore.com>

        * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
        sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
        elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
        Fix lower bound of tables.
        Add rep clauses.

        * nlists.adb: Ditto.
        (Prev_Node, Next_Node): Change index type to Int so that it properly
        covers the range First_Node_Id - 1 up.

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

            Robert Dewar  <dewar@adacore.com>

        * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
        Terminated: Add unchecked type conversion from System.Address to
        System.Tasking.Task_Id when calling the predefined primitive
        _disp_get_task_id.
        Disable new Ada 05 accessibility check for JVM.NET targets, which
        cannot be implemented in a practical way.
        (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
        the sources always references the tag of the actual object. Therefore,
        if 'Tag is applied in the sources to class-wide interface objects we
        generate code that displaces "this" to reference the base of the object.
        (Expand_N_Attribute_Reference, case Size): Return specified size if
        known to front end.
        (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
        has code that displaces the pointer of the object to manage interface
        types. However this code must not be executed when the prefix is a
        subprogram. This bug caused the wrong expansion of the internally
        generated assignment that fills the dispatch table when the primitive
        is a function returning a class-wide interface type.
        (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
        Set_Attribute_Name for Name_Unaligned_Valid.

2007-06-06  Ed Schonberg  <schonberg@adacore.com>

        * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
        If the initialization is the equivalent aggregate of the initialization
        procedure of the type, do not remove it.
        (Expand_N_Attribute_Definition_Clause): Exclude access variables
        initialized to null from having their expression reset to empty and
        note this exception in the comment.

        * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
        Add "with" and "use" clauses for Sem_Attr.
        (Expand_Current_Value): Do not replace occurences of attribute
        references where the prefix must be a simple name.

        * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
        Namet. Add new arrays Attribute_Name_Modifies_Prefix and
        Attribute_Requires_Simple_Name_Prefix.
        (Name_Modifies_Prefix): Body of new function.
        (Requires_Simple_Name_Prefix): Body of new function.
        (Resolve_Attribute, case Access): Improve error message for case of
        mismatched conventions.
        (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
        incomplete type.
        (Analyze_Attribute, case 'Access): If the type of the prefix is a
        constrained subtype for a nominal unconstrained type, use its base type
        to check for conformance with the context.
        (Resolve_Attribute): Remove test of the access type being associated
        with a return statement from condition for performing accessibility
        checks on access attributes, since this case is now captured by
        Is_Local_Anonymous_Access.
        (Analyze_Access_Attribute): Set Address_Taken on entity
        (Analyze_Attribute, case Address): Set Address_Taken on entity
        (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
        validating an access attribute whose prefix is a current instance.
        (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
        applied to dispatching operations, if freezing is required then we set
        the attribute Has_Delayed_Freeze in the prefix's entity.
        (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
        current scope if access of local subprogram taken
        (Analyze_Access_Attribute): Check legality of self-reference even if the
        expression comes from source, as when a single component association in
        an aggregate has a box association.
        (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
        the prefix if it is a protected operation and the attribute is
        Unrestricted_Access.
        (Resolve_Attribute, case 'Access): Set the Etype of the attribute
        reference to the base type of the context, to force a constraint check
        when the context is an access subtype with an explicit constraint.
        (Analyze_Attribute, case 'Class): If the prefix is an interface and the
        node is rewritten as an interface conversion. leave unanalyzed after
        resolution, to ensure that type checking against the context will take
        place.

            Robert Dewar  <dewar@adacore.com>

        * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
        wrapper when the full view of the controlling type of an inherited
        function that dispatches on result implements interfaces.
        (Expand_N_Object_Declaration): In cases where the type of the
        declaration is anonymous access, create finalization list for it.
        (Expand_N_Object_Declaration): Generate a persistent_bss directive only
        if the object has no explicit initialization, to match description of
        functionality of pragam Persistent_BSS.
        (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
        new function to build static aggregates, to replace initialization call
        when static initialization is desired.
        (Freeze_Type): Generate a list controller for an access type whenever
        its designated type has controlled anonymous access discriminants.
        (Build_Equivalent_Aggregate): New procedure to compute a static
        aggregate to be used as default initialization for composite types,
        instead of a generating a call to the initialization procedure for the
        type.
        (Build_Initialization_Call): When available, replace a call to the
        initialization procedure with a copy of the equivalent static aggregate
        for the type.
        (Expand_N_Object_Declaration):  Use New_Occurrence_Of in generated
        declarations for objects of a class-wide interface type, rather than
        just identifiers, to prevent visibility problems.
        (Expand_N_Object_Declaration): When expanding the declaration for an
        object of a class-wide interface type, preserve the homonym chain of
        the original entity before exchanging it with that of the generated
        renaming declaration.
        (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
        active, because there is no way to handle the exception.
        (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
        to do a minimum decoration of the Access_Disp_Table list.
        (Expand_Record_Controller): Avoid the addition of the controller between
        the component containing the tag of a secondary dispatch table and its
        adjacent component that stores the offset to the base of the object.
        This latter component is only generated when the parent type has
        discriminants ---documented in Add_Interface_Tag_Components).
        (Apply_Array_Size_Check): Removed, no longer needed.
        (Expand_N_Full_Type_Declaration): If the type has anonymous access
        components, create a Master_Entity for it only if it contains tasks.
        (Build_Init_Procedure): Suppress the tag assignment compiling under
        no run-time mode.
        (Freeze_Record_Type): Remove code associated with creation of dispatch
        table.
        (Init_Secondary_Tags): Update type of actuals when generating calls to
        Ada.Tags.Set_Offset_To_Top
        (Stream_Operation_OK): Disable use of streams compiling under no
        run-time mode
        (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
        if Has_Init_Expression set.
        (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
        Register_Primitive, which provides the same functionality.
        (Requires_Init_Proc): Return false in case of interface types.
        (Add_Secondary_Tables): Use the new attribute Related_Interface to
        cleanup the code.
        (Predefined_Primitive_Freeze): Do not assume that an internal entity
        is always associated with a predefined primitive because the internal
        entities associated with interface types are not predefined primitives.
        Therefore, the call to Is_Internal is replaced by a call to the
        function Is_Predefined_Dispatching_Operation.
        (Make_Eq_If): When generating the list of comparisons for the
        components of a given variant, omit the controller component that is
        present if the variant has controlled components.

            Bob Duff  <duff@adacore.com>

        * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
        handle the creation of finalization lists and calls for nested
        coextensions when the root of the chains is part of a return statement.
        (Inside_A_Return_Statement): New function inside Complete_Coextension_
        Finalization.
        (Expand_Record_Equality): Skip components that are interface types.
        (Displace_Allocator_Pointer): Add missing support for interface subtypes
        (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
        with Rewrite_Coextension. Change the condition for detecting coextension
        root nodes.
        (Is_Local_Access_Discriminant): Removed.
        (Rewrite_Coextension): New routine which rewrites a static coextension
        as a temporary and uses its unrestricted access in the construction of
        the outer object.
        (Complete_Coextension_Finalization): New routine. Generate finalization
        attachment calls to all delayed coextensions.
        (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
        the allocator is not a coextension itself and has delayed coextensions.
        If the current allocator is controlled, but also a coextension, delay
        the generation of the finalization attachment call.
        Rename local variable "Node" to "Nod" in order to avoid confusion with
        "Elists.Node".
        (Expand_Allocator_Expression): Call Adjust for initialized allocators of
        limited types that are not inherently limited. Such an allocator is
        illegal, but is generated by the expander for a return statement, to
        copy the result onto the secondary stack. This is the only case where a
        limited object can be copied. Generate code to displace the pointer
        to the object if the qualified expression is a class-wide interface
        object. Such displacement was missing and hence the copy of the object
        was wrong.
        (Apply_Accessibility_Check): Handle allocated objects initialized in
        place.
        (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
        and Expand_Allocator_Expression. Allocating class-wide interface objects
        this routine displaces the pointer to the allocated object to reference
        the component referencing the corresponding secondary dispatch table.
        Expand_Allocator_Expression): Add missing support to allocate class-wide
        interface objects initialized with a qualified expression.
        (Get_Allocator_Final_List): Test for an anonymous access type that is a
        function result type, and use the finalization list associated with the
        function scope in that case (such an anonymous type should not be
        treated like an access parameter's type).

        * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
        controlled type, use Make_Handler_For_Ctrl_Operation to construct the
        required exception handler.
        (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
        properly the case of a function whose return type is a limited
        class-wide interface type. Modify the code of the accessibility
        check to handle class-wide interface objects. In this case we need to
        displace "this" to reference the primary dispatch table to get access
        to the TSD of the object (to evaluate its accessibility level).
        (Expand_N_Extended_Return_Statement): Test for a tagged result type
        rather than a controlling result as one of the conditions for
        generating tests of the implicit BIP_Alloc_Form formal. The
        initialization assignment is also handled according to whether the
        result is tagged instead of controlling.
        In the case where the init assignment is inserted in the "then" part of
        the allocation conditional, rewrite the target to be a dereference of
        the implicit BIP_Object_Access formal.
        If the returned value is unconstrained and created on the secondary
        stack, mark the enclosing block and function so that the secondary
        stack is not reclaimed on return.
        Treat returns from functions with controlling results similarly to
        returns from functions with unconstrained result subtypes.
        If the object returned is unconstrained, and an allocator must be
        created for it, analyze the allocator once the block for the extended
        return is installed, to ensure that finalizable components
        of the expression use the proper finalization list. Guard the call to
        Move_Final_List with a check that there is something to finalize.
        (Make_Tag_Ctrl_Assignment): Use "old" handling
        of controlled type assignment for virtual machines, since new code uses
        unsupported features (such as direct access to bytes in memory).

2007-06-06  Gary Dismukes  <dismukes@adacore.com>
            Ed Schonberg  <schonberg@adacore.com>

        * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
        accessibility actual, check for the case of an aliased object that has
        been rewritten as an Access attribute, and assign Prev to Prev_Orig so
        we fall into processing for the attribute rather than the name of the
        object.
        (Expand_Inline_Call): If an actual is a literal, and the corresponding
        formal has its address taken in the body, create a temporary to capture
        value.  If the return type is a limited interface, do not treat the
        return value as Controlled.
        (Is_In_Place_Function):  If the return type is a limited interface,
        treat as returning in place. The actual returned object may not always
        be limited, but the caller has to assume that it is returned in place.
        (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
        context of an allocator, use the correct finalization chain (that is,
        the chain belonging to the access type, rather than the chain belonging
        to the current scope).
        (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
        result type rather than a controlling result as a precondition for
        adding an allocation form actual to a build-in-place call.
        (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
        (Freeze_Subprogram): Code cleanup. Remove all the code that register the
        primitive in the dispatch tables. This work is now done by Make_DT when
        the type is frozen.
        (Register_Predefined_DT_Entry): Removed.
        (Add_Return): If end label is not present, use sloc of last statement
        for generated return statement in procedure, for better gdb behavior
        on expanded code.
        (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
        object address nodes to ensure proper processing by routines like
        Insert_After*.
        (Expand_Call): Fix generation of validity check for parameter
        (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
        the allocation form parameter if the result subtype is constrained,
        except when the function has a controlling result.
        (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
        rather than Is_Controlled and Has_Controlled_Component, since we want to
        include class-wide result types in this treatment. Also test for a
        controlling result, since that also requires passing a finalization
        list.
        (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
        even when the result subtype is constrained, to handle calls involving
        controlling results.
        (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
        is now called even when the result subtype is constrained, to handle
        calls involving controlling results.
        (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
        on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
        now performs the test).
        (Make_Build_In_Place_Call_In_Object_Declaration):
        Add_Alloc_Form_Actual_* is now called even when the result subtype is
        constrained, to handle calls involving controlling results.
        (Add_Return): Accomodate rewritten pattern from local raise to goto
        transformation, so that we still recognize an transfer statement
        and do the right thing here in that case.
        (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
        and end of subprogram code.
        (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
        support for primitives that are functions (without formals) with a
        controlling result.
        (Inherited_From_Formal): If the actual subtype has not generic parent
        type, it is not an actual for a formal derived type, and there is no
        operation to inherit from the formal.

            Thomas Quinot  <quinot@adacore.com>

        * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
        inserted cleanup code appropriately for GDB use.
        (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
        exception handler for Deep_Adjust or Deep_Finalize.
        (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
        Raise_From_Controlled_Operation is available, use a call to that
        subprogram instead of a plain "raise Program_Error" node to raise
        Program_Error if an exception is propagated from an Adjust or Finalize
        operation.
        (Insert_Actions_In_Scope_Around): If the statement to be wrapped
        appears in the optional statement list of a triggering alternative, the
        scope actions can be inserted directly there, and not in the list that
        includes the asynchronous select itself.

        Deal properly with No_Exception_Propagation restriction mode.
        (Expand_N_Abort_Statement): Add an unchecked type conversion from
        System.Address to System.Tasking.Task_Id when processing the result of
        the predefined primitive _disp_get_task_id.
        (Expand_N_Asynchronous_Select): Clarify comment.
        (Expand_N_Protected_Type_Declaration): Minor code cleanup.
        (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.

        (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
        privals and for generated call to Complete_Entry_Body, for better gdb
        behavior.
        (Copy_Result_Type): Utility to construct a parameter and result profile
        for protected functions whose return type is an anonymous access to
        subprogram.
        (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
        call the above.
        (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
        point when the local-raise-to-goto transformation has taken place.

            Nicolas Setton  <setton@adacore.com>

        * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
        functionality when the backend is generating code.
        Otherwise any serious error
        reported by the backend calling the frontend routine Error_Msg
        changes the Compilation_Mode to Check_Semantics, disables the
        functionality of this routine and causes the generation of
        spureous additional errors.

        * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
        debugging information now generated by the compiler for fat-pointer
        types.
        Document the contents of DW_AT_producer in the GNAT Vendor extensions to
        DWARF2/3.
        Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.

2007-06-06  Thomas Quinot  <quinot@adacore.com>

        (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
        PolyORB_Support.Build_Subprogram_Receiving_Stubs):
        For a remote call to a function with a classwide return type, apply an
        E.4(18) check to the returned value.
        (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
        stream attributes of the designated type of an RACW, as they are not
        dispatching primitive operations.

2007-06-06  Geert Bosch  <bosch@adacore.com>

        * exp_fixd.adb (Integer_Literal): Add optional argument to construct a

        attribute compiling package Ada.Tags under No_Run_Time_Mode.

2007-06-06  Javier Miranda  <miranda@adacore.com>

        * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
        deallocation of class-wide interface objects.
        (Expand_Dispatching_Constructor_Call): Take into account that if the
        result of the dispatching constructor is an interface type, the
        function returns a class-wide interface type; otherwise the returned
        object would be actual. The frontend previously accepted returning
        interface types because Expand_Interface_Actuals silently performed
        the management of the returned type "as if" it were a class-wide
        interface type.
        (Expand_Dispatching_Constructor_Call): Replace call to
        Make_DT_Access_Action by direct call to Make_Function_Call.

            Ed Schonberg  <schonberg@adacore.com>

        * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
        compute masking constant, since we now set Esize properly to the
        underlying size.
        (Create_Packed_Array_Type): Set proper Esize value adjusted as required
        to match the alignment.
        (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for

        only if it is an access parameter.
        Increase size of C convention enumeration object
        (Freeze_Entity, array type case): Make sure Esize value is properly
        adjusted for the alignment if it is known.
        (Freeze_Entity, array type case): When checking bit packed arrays for
        the size being incorrect, check RM_Size, not Esize.
        (Freeze_Record_Type): Check for bad discriminated record convention
        (In_Exp_Body): Return true if the body is generated for a subprogram
        renaming, either an attribute renaming or a renaming as body.
        (Check_Itype): If the designated type of an anonymous access component
        is a non-protected subprogram type, indicate that it is frozen, to
        prevent out-of-scope freeze node at some subsequent call.
        (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
        only if the subprogram is neither imported nor exported, as well as the
        NCA descriptor class if the subprogram is exported.

        (Expand_Pragma_Assert): Add handling of No_Exception_Propagation
        restriction

        * snames.h, snames.ads, snames.adb, par-prag.adb: New pragma
        Static_Elaboration_Desired.

        Pragma_CIL_Constructor): New names.

        * sem_cat.adb (Validate_Object_Declaration): An initialization that

        to apply Import to an object renaming declaration.

        * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
        from a C++ class should be declared as limited and that it will be
        considererd limited.
        (Analyze_Pragma): Warn that a type specified with pragma CPP_Class

        absence of strange size or stream size clauses.
        (Build_Elementary_Write_Call): Same fix
        (Has_Stream_Standard_Rep): Returns False if Stream_Size attribute
        set to value that does not match base type size.

2007-06-06  Ed Schonberg  <schonberg@adacore.com>

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

        Add new warning for renaming of function return objects

        * opt.adb (Tree_Write, Tree_Read): Use proper expressions for size
        (Tree_Read): Use size of object instead of type'object_size, since the

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

        Standard can be renamed.
        (Analyze_Object_Renaming): Add new warning for renaming of function
        return objects.
        Also reject attempt to rename function return object in Ada 83 mode.

        generated function to the freezing actions of the type.
        (Find_Type): A protected type is visible right after the reserved word
        "is" is encountered in its type declaration. Set the entity and type

        memory in traces.
        (Allocate): Compute Storage_Address using Integer_Address, not
        Storage_Offset, because the range of Storage_Offset may not be large
        enough.
        (Configure): New parameter Low_Level_Traces
        (Allocate, Deallocation, Free_Physically): Added low-level traces
        (Configure): new parameter Errors_To_Stdout.

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

            Olivier Hainque  <hainque@adacore.com>

        * init.c: Do not adjust IP of an imported VMS exception of ia64.

        grandparent of the entity.
        (Analyze_Formal_Interface_Type): Transform into a full type declaration,
        to simplify handling of formal interfaces that derive from other formal
        interfaces.

        declaration, to ensure that the interface list is processed correctly.
        (Inline_Instance_Body): If enclosing scope is an instance body, remove
        its entities from visibiility as well.
        (Pre_Analyze_Actuals): if the actual is an allocator with  constraints
        given with a named association, analyze the expression only, not the
        discriminant association itself.
        (Reset_Entity): If the analysis of a selected component is transformed
        into an expanded name in the prefix of a call with parameters, do not
        transform the original node into an expanded name, to prevent visibility
        errors in the case of nested generics.
        (Check_Private_View): For an array type, check whether the index types
        may need exchanging.

        containing the offset to the base of the object (this latter component

        in this routine).
        (Inherit_Components): Use the new decoration of the tag components to
        improve the condition that avoids inheriting the components associated
        with secondary tags of the parent.
        (Build_Discriminanted_Subtype): Indicate to the backend that the
        size of record types associated with dispatch tables is known at

        field.
        (Add_Interface_Tag_Components.Add_Tag): Set the value of the attribute

        of the type that specify the position of interface tags when the type
        inherits discriminated array components from the parent type.
        If a component is initialized with a box, check for the presence of a
        default expression in its declaration before using its default
        initialization procedure.
        (Resolve_Record_Aggregate): If a component is box-initialized, and the
        component type has a discriminants, create a partial aggregate for it
        by copying the discriminants of the component subtype.
        Reject attempt to initialize a discriminant with a box.
        (Array_Aggr_Subtype): Indicate to the backend that the size of arrays
        associated with dispatch tables is known at compile time.
        (Get_Value): If an association in a record aggregate has a box
        association, and the corresponding record component has a default
        expression, always copy the default expression, even when the
        association has a single choice, in order to create a proper
        association for the expanded aggregate.

        not null indicator.

        * par-ch3.adb (P_Known_Discriminant_Part_Opt, P_Component_Items): If

        unimplemented unit.
        (Analyze_With_Clause): Recognize use of GNAT.Exception_Traces in a

        optimization of local raise to goto.
        (Analyze_With_Clause): Check for Most_Recent_Exception being with'ed,

        routines if the expander is not active.
        (Analyze_Task_Body): Mark all handlers to stop optimization of local

        (Resolve_Call): If the call returns an array, the context imposes the
        component type of the array, and the function has one non-defaulted
        parameter, rewrite the call as the indexing of a call with a single

        the master of the created object is the innermost enclosing statement.
        (Remove_Conversions): For a binary operator, check if type of second

        statement without using the full inlining machinery, for efficiency
        and to avoid invalid values in source file table entries.

        * exp_ch8.adb (Expand_N_Object_Renaming_Declaration): Add support for
        renamings of calls to build-in-place functions.

        (Entity): New subprogram that returns the entity for the referened
        unit. If this unit has not been loaded, it returns Empty.
        (RTE): Addition of a new formal that extends the search to the scopes
        of the record types found in the chain of the package.

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

        * sem_attr.adb (Build_Access_Object_Type): Use E_Access_Attribute_Type
        for all access attributes, because overload resolution should work the
        same for 'Access, 'Unchecked_Access, and 'Unrestricted_Access. This
        causes the error message for the ambiguous "X'Access = Y'Access" and
        "X'Unrestricted_Access = Y'Access" and so forth to match.
        (Resolve_Attribute, case 'Access): Remove use of Original_Access_Type,

        that use (a subtype of) the class-wide type of the enclosing type.
        (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
        Derived_Type for Prev formal on call to
        Check_Anonymous_Access_Components rather than Empty.
        (Make_Incomplete_Type_Declaration): Add test for case where the type has
        a record extension in deciding whether to create a class-wide type,
        rather than just checking Tagged_Present.
        (Replace_Anonymous_Access_To_Protected_Subprogram): Procedure applies
        to stand-alone object declarations as well as component declarations.
        (Array_Type_Declaration): Initialize Packed_Array_Type to Empty, to

        the associated_node for the itype is the type declaration itself.

        with abstract interfaces.
        (Analyze_Subtype_Indication): Resolve the range with the given subtype

        to private type.
        (Analyze_Subtype_Declaration): For an access subtype declaration, create

        gnatbind if the ALI file effectively exists.
        (Initialize): Add the directory where gnatmake is invoked in front of

        information, so that the correct GNAT tools will be used when spawned
        without directory information.

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

        accessibility on class-wide allocators if the allocator occurs at the
        same scope level as the allocator's type. The check is guaranteed to
        succeed in that case, even when the expression originates from a
        parameter of the containing subprogram.
        (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
        under No_Dispatching_Calls restriction. During the semantic analysis

        initialize most the TSD components by means of an aggregate.
        Modify the declaration of the object containing the TSD
        because we now expand code that has a higher level of abstraction.
        The TSD has a discriminant containing the Inheritance Depth Level,
        value that is used in the membership test but also to fix the size
        of the table of ancestors.
        (Expand_Interface_Conversion): Insert function body at the closest place
        to the conversion expression, to prevent access-before-elaboration

        the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_
        Op_Address by calls to Build_Set_Predefined_Prim_Op_Address, and
        Build_Set_Prim_Op_Address.
        (Get_Remotely_Callable): Subprogram removed.
        (Init_Predefined_Interface_Primitives): Replace generation of call to
        the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
        Prims.

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

        support concurrent types implementing interfaces.
        (Find_Implemented_Interface): Removed. All the calls to this subprogram
        specify kind Any_Limited_Interface, and this functionality is already
        provided by the function Has_Abstract_Interfaces.
        (Remove_Side_Effects): replace Controlled_Type by
        CW_Or_Controlled_Type whenever the issue is related to
        using or not the secondary stack.

        * par-ch12.adb (P_Formal_Type_Definition): Update calls to

        type, do not create a new itype for each protected body.
        If the body of a protected operation creates
        controlled types (including allocators for class-widetypes), the
        body of the corresponding protected subprogram must include a
        finalization list.

        parameter that requires an extra constrained parameter, declare
        temporary for actual as a variable, not a constant.
        (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
        the unit being compiled is the one that contains the stub type.
        Change primitive operation name for the RACW associated with a RAS
        from Call to _Call so it cannot clash with any legal identifier.
        (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
        Is_RAS.
        (Append_RACW_Bodies): New subprogram.
        (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
        Add_Receiving_Stubs_To_Declarations functions.
        When expanding a package body, this list correspond to the
        statements in the HSS at the end of the pacakge.
        When expanding a package spec, this list correspond to the
        spec declarations.
        (Add_Receiving_Stubs_To_Declarations): Append the function
        registering the receiving stubs at the end of the 'Stmts' list.
        (RCI_Package_Locator): Pass the new Version generic formal when
        instantiating a RCI_Locator package.
        (Build_From_Any_Function): To compute the High bound for an
        unconstrained array actual, we add the Low bound with the length.
        Thus we must convert the low bound and the length to an appropriate
        type before doing the sum.
        (Build_Subprogram_Receiving_Stubs, PolyORB):
         * Retrieve the extra formals parameters at the
           end of the parameter stream.
         * Use Move_Any_Value to write back out parameters
           after executing the request as it is more efficient
           than Copy_Any_Value.
         * Build the any containing Extra Formals with the
           appropriate typecode.
        (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
        empty Component_List.
        (Build_Actual_Object_Declaration): New subprogram. Build and insert into
        the tree the declaration for an object that serves as actual parameter
        in server-side stubs.
        (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
        PolyORB_Support.Build_Subprogram_Receiving_Stubs):
        Use Build_Actual_Object_Declaration to prepare the actuals.
        (Add_Parameter_To_NVList): Set the parameter mode to In for
        Extra Constrained Parameters.
        (Build_General_Calling_Stubs): Set the parameter type to boolean for

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

        the default project path, initially done during elaboration of the
        package.
        If the prefix returned by Sdefault is null, get the prefix from a call
        to Executable_Prefix_Path.
        (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
        null.

        * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non

        retrieved.
        (Record_Other_Sources): Idem.
        (Locate_Directory): Add the possibility to create automatically missing
        directories when Setup_Projects is True.
        Call Locate_Directory so that the directory will be created when
        Setup_Projects is True, for object dir, library dir, library ALI dir,
        library source copy dir and exec dir.

        * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older

        Expand_Limited_With_Clause): Use a new copy of selector name in the

        purposes. Nothing is changed in the compiler behaviour.
        (Process_Body_Clauses): Handle properly use clauses whose prefix is
        a package renaming.
        (Install_Limited_With_Clauses): Do not install non-limited view when it

        * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
        when capturing size information, instead of base type, which for a
        formal array type will be the unconstrained type.
        (Analyze_Formal_Object_Declaration): Add check for illegal default
        expressions for a formal in object of a limited type.
        (Instantiate_Object): Ditto.
        (Check_Formal_Package_Instance): Skip entities that are formal objects,
        because they were defaulted in the formal package and no check applies
        to them.
        (Check_Formal_Package_Instance): Extend conformance check to other
        discrete types beyond Integer.
        (Process_Default): Copy directly the unmatched formal. A generic copy
        has already been performed in Analyze_Formal_Package.
        (Analyze_Associations): If a formal subprogram has no match, check for
        partial parametrization before looking for a default, to prevent
        spurious errors.
        (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
        not set the instantiation environment before analyzing the actuals.
        Fixes regression on 8515-003 with implementation of AI-133.
        Set_Instance_Env checks whether the generic unit is a predefined
        unit, in which case the instance must be analyzed with the latest Ada
        mode. This setting must take place after analysis of the actuals,
        because the actuals must be analyzed and frozen in the Ada mode extant
        outside of the current instantiation.
        (Save_Env, Restore_Env): Preserve and restore the configuration
        parameters so that predefined units can be compiled in the proper Ada
        mode.
        (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
        Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
        and Is_Abstract_Type.
        (Analyze_Formal_Package): For better error recovery, Add exception
        handler to catch Instantion_Error, which can be raised in
        Analyze_Associations

        * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
        prefix type is a discriminated subtype of the type of the formal.
        (Analyze_Allocator): Collect all coextensions regardless of the context.
        Whether they can be allocated statically is determined in exp_ch4.
        (Analyze_Selected_Component): If the prefix is a limited view and the
        non-limited view is available, use the non-limited one.
        (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
        therefore illegal), suggest a qualified expression rather than a type
        conversion, because a type conversion would be illegal in this context.
        (Anayze_Allocator): Trace recursively all nested allocators so that all
        coextensions are on the corresponding list for the root. Do no mark
        coextensions if the root allocator is within a declaration for a stack-
        allocated object, because the access discriminants will be allocated on
        the stack as well.
        (Analyze_Call): Remove restriction on calls to limited functions for the
        cases of generic actuals for formal objects, defaults for formal objects
        and defaults for record components.
        (Analyze_Allocator): Before analysis, chain coextensions on the proper
        element list. Their expansion is delayed until the enclosing allocator
        is processed and its finalization list constructed.
        (Try_Primitive_Operation): If the prefix is a concurrent type, looks
        for an operation with the given name among the primitive operations of
        the corresponding record type.
        (Analyze_Selected_Component): If the prefix is a task type that
        implements an interface, and there is no entry with the given name,
        check whether there is another primitive operation (e.g. a function)
        with that name.
        (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
        properly the indexing of a function call written in prefix form, where
        the function returns an array type, and all parameters of the function
        except the first have defaults.
        (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
        the original operands, rather than relocating them, for efficiency and
        to work properly when an operand is overloaded.
        (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
        Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
        (Analyze_Selected_Component): If the prefix is a private extension, only
        scan the visible components, not those of the full view.
        (Try_Primitive_Operation): If the operation is a procedure, collect all
        possible interpretations, as for a function, because in the presence of
        classwide parameters several primitive operations of the type can match
        the given arguments.

            Robert Dewar  <dewar@adacore.com>

        * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
        tag-indeterminate call to an abstract function, when the left-hand side
        is not classwide.
        (Analyze_Loop_Statement): Improve detection of infinite loops

            Thomas Quinot  <quinot@adacore.com>

        * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
        out of Analyze_Package_Declaration, because processing must be applied
        to package bodies as well, for deferred constants completed by pragmas.
        (Analyze_Package_Declaration): When the package declaration being
        analyzed does not require an explicit body, call Check_Completion.
        (May_Need_Implicit_Body): An implicit body is required when a package
        spec contains the declaration of a remote access-to-classwide type.
        (Analyze_Package_Body): If the package contains RACWs, append the
        pending subprogram bodies generated by exp_dist at the end of the body.
        (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
        Is_Abstract_Subprogram and Is_Abstract_Type.
        (Preserve_Full_Attributes): The full entity list is not an attribute
        that must be preserved from full to partial view.

        * sem_dist.adb (Add_RAS_Dereference_TSS):
        Change primitive name to _Call so it cannot clash with any legal
        identifier, and be special-cased in Check_Completion.
        Mark the full view of the designated type for the RACW associated with
        a RAS as Comes_From_Source to get proper view switching when installing
        private declarations.
        Provite a placeholder nested package body along with the nested spec
        to have a place for Append_RACW_Bodies to generate the calling stubs
        and stream attributes.

        * sem_ch8.adb (Has_Components): If the argument is an incomplete type
        that is a limited view, check the non-limited view if available.
        (Undefined): Refine error message for missing with of Text_IO
        (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
        to distinguish real missing with cases.
        Fix format of all missing with messages
        (Analyze_Subprogram_Renaming): Emit proper error message on illegal
        renaming as body when renamed entity is abstract.

            Javier Miranda  <miranda@adacore.com>

        * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
        predicate recursive, to handle complex expressions on literals whose
        spurious ambiguity comes from the abstract interpretation of some
        subexpression.
        (Interface_Present_In_Ancestor): Add support to concurrent record
        types.
        (Add_One_Interp,Disambiguate): Split Is_Abstract flag into

            Javier Miranda  <miranda@adacore.com>

        * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
        dereference of a local object R created as a reference to another
        object O, use the access level of O.
        (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
        rather than local Same_Formal_Type, to check whether protected operation
        overrides an inherited one.
        (Same_Formal_Type): New predicate, used when matching signatures of
        overriding synchronized operations, to handle the case when a formal
        has a type that is a generic actual.
        (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
        predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
        (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
        syntactic ambiguities involving indexing of function calls that return
        arrays.
        (Abstract_Interface_List): New subprogram that returns the list of
        abstract interfaces associated with a concurrent type or a
        concurrent record type.

        with interface types.
        (Has_Abstract_Interfaces): Add support for concurrent types with
        interface types.
        (Is_Parent): New subprogram that determines whether E1 is a parent
        of E2. For a concurrent type its parent is the first element of its
        list of interface types; for other types this function provides the
        same result than Is_Ancestor.
        (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
        (Collect_Synchronized_Interfaces): Removed because the subprogram
        Collect_Abstract_Interfaces provides this functionality.
        (Collect_Abstract_Interfaces): Minor update to give support to
        concurrent types and thus avoid undesired code duplication.
        (Get_Subprogram_Entity): Handle entry calls.
        (May_Be_Lvalue): Include actuals that appear as in-out parameters in
        entry calls.
        (Enter_Name): Do not give -gnatwh hiding warning for record component
        entities, they never result in hiding.

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

        (UI_Div): Reimplement as a call to UI_Div_Rem.
        (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
        remainder, avoiding the cost of a multiplication and a subtraction.
        (UI_Modular_Inverse): Take advantage of the fact that UI_Div_Rem
        provides both quotient and remainder in a single computation.
        (UI_Modular_Exponentiation, UI_Modular_Inverse): New modular arithmetic
        functions for uint.

        (Executable_Prefix.Get_Install_Dir): First get the full path, so that
        we find the 'lib' or 'bin' directory even when the tool has been

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

        * exp_attr.adb: 
        (Expand_Access_To_Protected_Op): If the context indicates that an access
        to a local operation may be transfered outside of the object, create an
        access to the wrapper operation that must be used in an external call.
        (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
        target, pass the Valid attribute applied to a floating-point prefix on
        to the back end without expansion.
        (Storage_Size): Use the new run-time function Storage_Size to retrieve
        the allocated storage when it is specified by a per-object expression.
        (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
        Nothing to do here, the attribute has been rewritten during semantic
        analysis.
        (Expand_Attribute_Reference): Handle expansion of the new Priority
        attribute
        (Find_Fat_Info): Handle case of universal real
        (Expand_Access_To_Protected_Op): Fix use of access to protected
        subprogram from inside the body of a protected entry.
        (Expand_Access_To_Protected_Op): Common procedure for the expansion of
        'Access and 'Unrestricted_Access, to transform the attribute reference
        into a fat pointer.
        (Is_Constrained_Aliased_View): New predicate to help determine whether a
        subcomponent's enclosing variable is aliased with a constrained subtype.
        (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
        test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
        an aliased prefix must be known to be constrained in order to use True
        for the attribute value, and now it's possible for some aliased views
        to be unconstrained.

            Gary Dismukes  <dismukes@adacore.com>

        * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
        register in the final list objects containing class-wide interfaces;
        otherwise we incorrectly register the tag of the interface in the final
        list.
        (Make_Controlling_Function_Wrappers): Add missing barrier to do not
        generate the wrapper if the parent primitive is abstract. This is
        required to report the correct error message.
        (Expand_N_Subtype_Indication): Do validity checks on range
        (Clean_Task_Names): If an initialization procedure includes a call to
        initialize a task (sub)component, indicate that the procedure will use
        the secondary stack.
        (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
        compatibility for interfacing with CPP by default.
        (Expand_N_Object_Declaration): Only build an Adjust call when the
        object's type is a nonlimited controlled type.
        * exp_ch3.adb: Add with and use of Exp_Ch6.
        (Expand_N_Object_Declaration): Check for object initialization that is a
        call to build-in-place function and apply Make_Build_In_Place_Call_In_
        Object_Declaration to the call.
        (Freeze_Type): When the designated type of an RACW was not frozen at the
        point where the RACW was declared, validate the primitive operations
        with respect to E.2.2(14) when it finally is frozen.
        (Build_Initialization_Call,Expand_Record_Controller): Rename
        Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
        return-by-reference has no meaning in Ada 2005.
        (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
        to register tag of the immediate ancestor interfaces in the
        run-time structure.
        (Init_Secondary_Tags): Moved to the specification to allow the
        initialization of extension aggregates with abstract interfaces.
        (Build_Master_Renaming): Make public, for use by function declarations
        whose return type is an anonymous access type.
        (Freeze_Record_Type): Replace call to Insert_List_Before by call to
        Insert_List_Before_And_Analyze after the generation of the specs
        associated with null procedures.
        (Expand_Tagged_Root): Update documentation in its specification.
        (Init_Secondary_Tags): Update documentation.
        (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
        tibility mode and the immediate ancestor is a CPP_Pragma tagged type
        then generate code to inherit the contents of the dispatch table
        directly from the ancestor.
        (Expand_Record_Controller): Insert controller component after tags of
        implemented interfaces.
        (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
        create null procedure overridings when null procedures are inherited
        from interfaces.
        (Make_Null_Procedure_Specs): New procedure to generate null procedure
        declarations for overriding null primitives inherited from interfaces.
        (Is_Null_Interface_Procedure): New function in
        Make_Null_Procedure_Specs.
        (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
        immediate ancestor of a tagged type is an abstract interface type we
        must generate the specification of the predefined primitives associated
        with controlled types (because the dispatch table of the ancestor is
        null and hence these entries cannot be inherited). This is required to
        elaborate well the dispatch table.

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

        * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.

        * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
        (Expand_N_Assignment_Statement): Call
        Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
        build-in-place function call. Currently, this can happen only for
        assignments that come from aggregates.
        Add -gnatd.l --Use Ada 95 semantics for limited function returns,
        in order to alleviate the upward compatibility introduced by AI-318.
        (Expand_N_Extended_Return_Statement): Add support for handling the
        return object as a build-in-place result.
        (Expand_Non_Function_Return): Implement simple return statements nested
        within an extended return.
        (Enable_New_Return_Processing): Turn on the new processing of return
        statements.
        (Expand_Non_Function_Return): For a return within an extended return,
        don't raise Program_Error, because Sem_Ch6 now gives a warning.
        (Expand_N_Extended_Return_Statement): Implement AI-318
        (Expand_Simple_Function_Return): Ditto.
        (Expand_N_If_Statement): Handle new -gnatwt warning
        (Expand_N_Case_Statement): Handle new -gnatwt warning
        (Expand_N_Assignment): Handle assignment to the Priority attribute of
        a protected object.
        (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
        validity checking of assignments to elementary record components.
        (Expand_N_Return_Statement): return Class Wide types on the secondary
        stack independantly of their controlled status since with HIE runtimes,
        class wide types are not potentially controlled anymore.

        * expander.adb (Expand): Add case for new N_Extended_Return_Statement
        node kind.

        * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
        Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
        it expects a block, procedure, or task. The return statement will get
        turned into a block, and Expand_Cleanup_Actions will happen then.

        * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
        capability.
        (Expand_Inlined_Call): Tagged types are by-reference types, and
        therefore should be replaced by a renaming declaration in the expanded
        body, as is done for limited types.
        (Expand_Call): If this is a call to a function with dispatching access
        result, propagate tag from context.
        (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
        CPP by default.
        (Make_Build_In_Place_Call_In_Assignment): New procedure to do
        build-in-place when the right-hand side of an assignment is a
        build-in-place function call.
        (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
        of the explicit dereference of the allocator to the result subtype of
        the build-in-place function. This is needed to satisfy type checking
        in cases where the caller's return object is created by an allocator for
        a class-wide access type and the type named in the allocator is a
        specific type.
        (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
        conversion of the reference to the declared object to the result subtype
        of the build-in-place function. This is needed to satisfy type checking
        in cases where the declared object has a class-wide type. Also, in the
        class-wide case, change the type of the object entity to the specific
        result subtype of the function, to avoid passing a class-wide object
        without explicit initialization to the back end.
        (Register_Interface_DT_Entry): Moved outside the body of
        Freeze_Subprogram because this routine is now public; it is called from
        Check_Dispatching_Overriding to handle late overriding of abstract
        interface primitives.
        (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
        adding an implicit access actual on a call to a build-in-place function.
        (Expand_Actuals): Test for an actual parameter that is a call to a
        build-in-place function and apply
        Make_Build_In_Place_Call_In_Anonymous_Context to the call.
        (Is_Build_In_Place_Function): New function to determine whether an
        entity is a function whose calls should be handled as build-in-place.
        (Is_Build_In_Place_Function_Call): New function to determine whether an
        expression is a function call that should handled as build-in-place.
        (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
        calls to build-in-place functions as the initialization of an allocator.
        (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
        handling calls to build-in-place functions in contexts that do not
        involve init of a separate object (for example, actuals of subprogram
        calls).
        (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
        handling calls to build-in-place functions as the initialization of an
        object declaration.
        (Detect_Infinite_Recursion): Add explicit parameter Process to
        instantiation of Traverse_Body to avoid unreferenced warning.
        (Check_Overriding_Inherited_Interfaces): Removed.
        (Register_Interface_DT_Entry): Code cleanup.
        (Register_Predefined_DT_Entry): Code cleanup.
        (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
        inlined statements if within a transient scope.
        (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
        formal parameters with occurrences of actuals in inlined body, establish
        visibility on the proper view of the actual's subtype for the body's
        context.
        (Freeze_Subprogram): Do nothing if we are compiling under full ABI
        compatibility mode and we have an imported CPP subprogram because
        for now we assume that imported CPP primitives correspond with
        objects whose constructor is in the CPP side (and therefore we
        don't need to generate code to register them in the dispatch table).
        (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
        aligned selected component.
        (Add_Call_By_Copy_Node): Add missing code to handle the case in which
        the actual of an in-mode parameter is a type conversion.
        (Expand_Actuals): If the call does not come from source and the actual
        is potentially misaligned, let gigi handle it rather than rejecting the
        (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
        Class Wide types as returning by reference independantly of their
        controlled status since with HIE runtimes class wide types are not
        potentially controlled anymore.

        (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
        instantiation to deal with warnings.
        (Initialize_Protection): If expression for priority is non-static, use
        System_Priority as its expected type, in case the expression has not
        been analyzed yet.

        calling Assign_Subprogram_Ids if necessary.
        (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
        should be done only once they are assigned.
        (Build_From_Any_Function, case of tagged types): Add missing call to
        Allocate_Buffer.
        (Corresponding_Stub_Type): New subprogram. Returns the associated stub
        type for an RACW type.
        (Add_RACW_Features): When processing an RACW declaration for which the
        designated type is already frozen, enforce E.2.2(14) rules immediately.
        (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
        special reordering of controlling formals.

        * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
        associated stub type for an RACW type.

        assumption that Str'First = 1.
        (Value_Wide_Character): Takes EM (encoding method) parameter and passes
        it on to the Value_Wide_Wide_Character call.
        (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
        properly handles a string of the form quote-encoded_wide_char-quote.

        * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
        Machine_Attribute pragma internally to implement the user pragma.
        Add processing for pragma Interface so that it is now completely
        equivalent to pragma Import.

        * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
        so that it can be applied to all entities, including record components
        and enumeration literals.
        (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
        priority ranges are correct, verify compatibility against task
        dispatching and locking policies, and if everything is correct an entry
        is added to the table containing priority specific dispatching entries
        for this compilation unit.
        (Delay_Config_Pragma_Analyze): Delay processing
        Priority_Specific_Dispatching pragmas because when processing the
        pragma we need to access run-time data, such as the range of
        System.Any_Priority.
        (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
        Allow pragma Unreferenced as a context item
        Add pragma Preelaborable_Initialization
        (Analyze_Pragma, case Interface): Interface is extended so that it is
        now syntactically and semantically equivalent to Import.
        (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
        insertion characters.
        Add handling for Pragma_Wide_Character_Encoding
        (Process_Restrictions_Restriction_Warnings): Ensure that a warning
        never supercedes a real restriction, and that a real restriction
        always supercedes a warning.
        (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of
        appropriate form.

            Ed Schonberg  <schonberg@adacore.com>
            Robert Dewar  <dewar@adacore.com>

        * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
        Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
        Is_Inherently_Limited_Type, because return-by-reference has no meaning
        in Ada 2005.
        (Find_Node_To_Be_Wrapped): Use new method of determining the result
        type of the function containing a return statement, because the
        Return_Type field was removed. We now use the Return_Applies_To field.

        * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
        (Build_Task_Image_Decl): If procedure is not called from an
        initialization procedure, indicate that function that builds task name
        uses the sec. stack. Otherwise the enclosing initialization procedure
        will carry the indication.
        (Insert_Actions): Remove N_Return_Object_Declaration. We now use
        N_Object_Declaration instead.
        (Kill_Dead_Code): New interface to implement -gnatwt warning for
        conditional dead code killed, and change implementation accordingly.
        (Insert_Actions): Add N_Return_Object_Declaration case.
        Correct comment to mention N_Extension_Aggregate node.
        (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
        attempts to save information for global variables which cannot be
        safely tracked.
        (Get_Current_Value_Condition): Handle conditions the other way round
        (constant on left). Also handle right operand of AND and AND THEN
        (Set_Current_Value_Condition): Corresponding changes
        (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
        (Get_Current_Value_Condition): Handle simple boolean operands
        (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
        (Get_Current_Value_Condition): If the variable reference is within an
        if-statement, does not appear in the list of then_statments, and does
        not come from source, treat it as being at unknown location.
        (Get_Current_Value_Condition): Enhance to allow while statements to be
        processed as well as if statements.
        (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
        come from source.
        (OK_To_Do_Constant_Replacement): Allow constant replacement within body
        of loop. This is safe now that we fixed Kill_Current_Values.
        (OK_To_Do_Constant_Replacement): Check whether current scope is
        Standard, before examining outer scopes.

2006-10-31  Vincent Celier  <celier@adacore.com>

        * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
        When True, apply VMS treatment to children of packages A, G, I and S.
        For F320-016

        * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target

2006-10-31  Robert Dewar  <dewar@adacore.com>
            Ed Schonberg  <schonberg@adacore.com>

        * freeze.adb: Add handling of Last_Assignment field
        (Warn_Overlay): Supply missing continuation marks in error msgs
        (Freeze_Entity): Add check for Preelaborable_Initialization

        * g-comlin.adb: Add Warnings (Off) to prevent new warning

        * g-expect.adb: Add Warnings (Off) to prevent new warning

        * lib-xref.adb: Add handling of Last_Assignment field
        (Generate_Reference): Centralize handling of pragma Obsolescent here
        (Generate_Reference): Accept an implicit reference generated for a
        default in an instance.
        (Generate_Reference): Accept a reference for a node that is not in the
        main unit, if it is the generic body corresponding to an subprogram
        instantiation.

        * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings

        * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
        -gnatwq/Q.
        (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
        exception handler.
        (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
        use clauses, to avoid messages on packages used to qualify, and also
        to avoid messages from obsolescent units.
        (Warn_On_Useless_Assignments): Don't generate messages for imported
        and exported variables.
        (Warn_On_Useless_Assignments): New procedure
        (Output_Obsolescent_Entity_Warnings): New procedure
        (Check_Code_Statement): New procedure

        * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
        Change name Is_Ada_2005 to Is_Ada_2005_Only
        (Last_Assignment): New field for useless assignment warning

2006-10-31  Olivier Hainque  <hainque@adacore.com>

        * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
        closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.

2006-10-31  Bob Duff  <duff@adacore.com>
            Robert Dewar  <dewar@adacore.com>
            Ed Schonberg  <schonberg@adacore.com>

        * g-awk.adb (Default_Session, Current_Session): Compile this file in
        Ada 95 mode, because it violates the new rules for AI-318.

        * g-awk.ads: Use overloaded subprograms in every case where we used to
        have a default of Current_Session. This makes the code closer to be
        correct for both Ada 95 and 2005.

        * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
        code, relying on the fact that the compiler generates a warning
        instead of an error in -gnatg mode.

        * lib-xref.ads (Xref_Entity_Letters): Add entry for new
        E_Return_Statement entity kind.
        Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.

        * par.adb (P_Interface_Type_Definition): Addition of one formal to
        report an error if the reserved word abstract has been previously found.
        (SS_End_Type): Add E_Return for new extended_return_statement syntax.

        * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
        parenthesized range attribute usage
        (P_Expression_No_Right_Paren): Add missing comment about error recovery.

        * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
        in the syntax for extended_return_statement. This is not in the latest
        RM, but the ARG is expected to issue an AI allowing this.
        (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
        N_Return_Object_Declaration. We now use N_Object_Declaration instead.
        (P_Return_Object_Declaration, P_Return_Subtype_Indication,
        P_Return_Statement): Parse the new syntax for extended_return_statement.

        * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
        Output_End_Missing): Add error-recovery code for the new
        extended_return_statement syntax; that is, the new E_Return entry on
        the scope stack.

        * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
        limited to nonlimited, because otherwise we violate the new Ada 2005
        rules about returning limited types in function Create_AST_Handler in
        s-asthan.adb.

        * sem.adb (Analyze): Add cases for new node kinds
        N_Extended_Return_Statement and N_Return_Object_Declaration.

        * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
        type is in the same category as type of context before applying check,
        to prevent anomalies in instantiations.
        (Resolve_Aggregate): Remove test for limited components in aggregates.
        It's unnecessary in Ada 95, because if it has limited components, then
        it must be limited. It's wrong in Ada 2005, because limited aggregates
        are now allowed.
        (Resolve_Record_Aggregate): Move check for limited types later, because
        OK_For_Limited_Init requires its argument to have been resolved.
        (Get_Value): When copying the component default expression for a
        defaulted association in an aggregate, use the sloc of the aggregate
        and not that of the original expression, to prevent spurious
        elaboration errors, when the expression includes function calls.
        (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
        were missing. We also didn't handle qualified expressions. Now also
        allow function calls. Use new common routine OK_For_Limited_Init.
        (Resolve_Extension_Aggregate): Minor fix to bad error message (started
        with space can upper case letter).

        * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
        Has_Static_Discriminants flag
        (Record_Type_Declaration): Diagnose an attempt to declare an interface
        type with discriminants.
        (Process_Range_Expr_In_Decl): Do validity checks on range
        (Build_Discriminant_Constraints): Use updated form of
        Denotes_Discriminant.
        (Process_Subtype): If the subtype is a private subtype whose full view
        is a concurrent subtype, introduce an itype reference to prevent scope
        anomalies in gigi.
        (Build_Derived_Record_Type, Collect_Interface_Primitives,
        Record_Type_Declaration):  The functionality of the subprograms
        Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
        is now performed by a single routine.
        (Build_Derived_Record_Type): If the type definition includes an explicit
        indication of limitedness, then the type must be marked as limited here
        to ensure that any access discriminants will not be treated as having
        a local anonymous access type.
        (Check_Abstract_Overriding): Issue a detailed error message when an
        abstract subprogram was not overridden due to incorrect mode of its
        first parameter.
        (Analyze_Private_Extension_Declaration): Add support for the analysis of
        synchronized private extension declarations. Verify that the ancestor is
        a limited or synchronized interface or in the generic case, the ancestor
        is a tagged limited type or synchronized interface and all progenitors
        are either limited or synchronized interfaces.
        Derived_Type_Declaration): Check for presence of private extension when
        dealing with synchronized formal derived types.
        Process_Full_View): Enchance the check done on the usage of "limited" by
        testing whether the private view is synchronized.
        Verify that a synchronized private view is completed by a protected or
        task type.
        (OK_For_Limited_Init_In_05): New function.
        (Analyze_Object_Declaration): Move check for limited types later,
        because OK_For_Limited_Init requires its argument to have been resolved.
        Add -gnatd.l --Use Ada 95 semantics for limited function returns,
        in order to alleviate the upward compatibility introduced by AI-318.
        (Constrain_Corresponding_Record): If the constraint is for a component
        subtype, mark the itype as frozen, to avoid out-of-scope references to
        discriminants in the back-end.
        (Collect_Implemented_Interfaces): Protect the recursive algorithm of
        this subprogram against wrong sources.
        (Get_Discr_Value, Is_Discriminant): Handle properly references to a
        discriminant of limited type completed with a protected type, when the
        discriminant is used to constrain a private component of the type, and
        expansion is disabled.
        (Find_Type_Of_Object): Do not treat a return subtype that is an
        anonymous subtype as a local_anonymous_type, because its accessibility
        level is the return type of the enclosing function.
        (Check_Initialization): In -gnatg mode, turn the error "cannot
        initialize entities of limited type" into a warning.
        (OK_For_Limited_Init): Return true for generated nodes, since it
        sometimes violates the legality rules.
        (Make_Incomplete_Declaration): If the type for which an incomplete
        declaration is created happens to be the currently visible entity,
        preserve the homonym chain when removing it from visibility.
        (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
        inherited subprograms.
        (Access_Definition): If this is an access to function that is the return
        type of an access_to_function definition, context is a type declaration
        and the scope of the anonymous type is the current one.
        (Analyze_Subtype_Declaration): Add the defining identifier of a regular
        incomplete subtype to the set of private dependents of the original
        incomplete type.
        (Constrain_Discriminated_Type): Emit an error message whenever an
        incomplete subtype is being constrained.
        (Process_Incomplete_Dependents): Transform an incomplete subtype into a
        corresponding subtype of the full view of the original incomplete type.
        (Check_Incomplete): Properly detect invalid usage of incomplete types
        and subtypes.

2006-10-31  Arnaud Charlet  <charlet@adacore.com>
            Robert Dewar  <dewar@adacore.com>

        * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
        handling executable extension manually and duplicating code.

        * make.adb: Implement new -S switch
        (Gnatmake): Use new function Osint.Executable_Name instead
        of handling executable extension manually.

        * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
        is specified, the executable name ends with this suffix.
        Take advantage of Osint.Executable_Name instead of duplicating code.

        * switch-m.adb: Recognize new gnatmake -S switch

        * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
        variable.
        (Get_Target_Parameters): Set Executable_Extension_On_Target if
        available.

        * makeusg.adb: Add line for gnatmake -S switch

2006-10-31  Vincent Celier  <celier@adacore.com>

        * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
        call it with -static-libgcc, as there are some platforms, such as
        Darwin, where one of these two switches is compulsory to link.

2006-10-31  Vincent Celier  <celier@adacore.com>

        * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
        instead of ADA_PROJECT_PATH, for the project path.
        (Gnatls): When displaying the project path directories, use host dir
        specs.

        * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
        names in the project path, as absolute paths may correspond to
        multi-valued VMS logical names.

2006-10-31  Vincent Celier  <celier@adacore.com>

        * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
        absolute path name.
        (Locate_Regular_File): Ditto
        (Change_Dir): Remove, no longer used
        (Normalize_Pathname): Do not use Change_Dir to get the drive letter
        on Windows. Get it calling Get_Current_Dir.
        (OpenVMS): Remove imported boolean, no longer needed.
        (Normalize_Pathname)[VMS]: Do not resolve directory names.
        (Pid_To_Integer): New function to convert a Process_Id to  Integer

2006-10-31  Thomas Quinot  <quinot@adacore.com>

        * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
        sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
        to No_Socket.
        (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
        W_Sig_Socket.

2006-10-31  Robert Dewar  <dewar@adacore.com>

        * g-speche.ads, g-speche.adb: Add special case to recognize misspelling
        initial letter o as a zero.

2006-10-31  Robert Dewar  <dewar@adacore.com>

        * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
        variant records
        (Layout_Variant_Record): Retrieve the discriminants from the entity
        rather than from the type definition, because in the case of a full
        type for a private type we need to take the discriminants from the
        partial view.
        (Layout_Component_List): When applying the Max operator to variants with
        a nonstatic size, check whether either operand is static and scale that
        operand from bits to storage units before applying Max.
        (Layout_Type): In VMS, if a C-convention access type has no explicit
        size clause (and does not inherit one in the case of a derived type),
        then the size is reset to 32 from 64.

2006-10-31  Vincent Celier  <celier@adacore.com>

        * lib-load.adb (Load_Unit): Skip the test for a unit not found when
        its file has already been loaded, according to the unit being loaded,
        not to the current value of Multiple_Unit_Index.

2006-10-31  Thomas Quinot  <quinot@adacore.com>
            Eric Botcazou  <ebotcazou@adacore.com>
            Arnaud Charlet  <charlet@adacore.com>

        * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
        (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
        possible.
        (a-except.o): Pass it to the compiler.
        (gnatlib-shared-vms): Removed -nostartfiles switch in link step.
        (LIBGNAT_TARGET_PAIRS for Windows): Avoid the use of the specific
        a-calend-mingw.adb version.

        * Makefile.rtl: Added s-dsaser.
        Add object entries for Ada.Calendar.[Arithmetic/Formatting/Time_Zones]
        (GNATRTL_TASKING_OBJS): Add Ada.Dispatching and
        Ada.Dispatching.Round_Robin.
        Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists

        * Make-lang.in: Remove all references to gt-ada-decl.h.
        Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler

        * mlib-utl.adb (Initialized): Remove, no longer used
        (Initialize): Remove, no longer used
        (Ar): If Ar_Exec is null, get the location of the archive builder and,
        if there is one, the archive indexer. Fail if the archive builder cannot
        be found.
        (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
        be found.

2006-10-31  Ed Schonberg  <schonberg@adacore.com>

        * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
        Process_Body_Clauses): If the context of a body includes a use clause
        for P.Q then a with_clause for P in the same body is not redundant,
        even if the spec also has a with_clause on P.
        Add missing continuation mark to error msg
        (Build_Limited_Views): A limited view of a type is tagged if its
        declaration includes a record extension.
        (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
        node, even if the subunit has errors. This avoids malfunction by
        Lib.Check_Same_Extended_Unit in the presence of syntax errors.
        (Analyze_Compilation_Unit): Add circuit to make sure we get proper
        generation of obsolescent messages for with statements (cannot do
        this too early, or we cannot implement avoiding the messages in the
        case of obsolescent units withing obsolescent units).
        (Install_Siblings): If the with_clause is on a remote descendant of
        an ancestor of the current compilation unit, find whether there is
        a sibling child unit that is immediately visible.
        (Remove_Private_With_Clauses): New procedure, invoked after completing
        the analysis of the private part of a nested package, to remove from
        visibility the private with_clauses of the enclosing package
        declaration.
        (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
        now centralized in Generate_Reference.
        (Install_Limited_Context_Clauses): Remove superfluous error
        message associated with unlimited view visible through use
        and renamings. In addition, at the point in which the error
        is reported, we add the backslash to the text of the error
        to ensure that it is reported as a single error message.
        Use new // insertion for some continuation messages
        (Expand_Limited_With_Clause): Use copy of name rather than name itself,
        to create implicit with_clause for parent unit mentioned in original
        limited_with_clause.
        (Install_Limited_With_Unit): Set entity of parent identifiers if the
        unit is a child unit. For ASIS queries.
        (Analyze_Subunit): If the subunit appears within a child unit, make all
        ancestor child units directly visible again.

        a formal object declaration with an access definition or a subtype mark
        with a null exclusion.
        (P_Generic_Association): Handle association with box, and others_choice
        with box, to support Ada 2005 partially parametrized formal packages.

        after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
        (P_Type_Declaration): Minor code cleanup. Add support for synchronized
        private extensions.
        (P_Type_Declaration): Add the new actual Abstract_Present to every call
        to P_Interface_Type_Definition.
        (P_Interface_Type_Definition): Addition of one formal to report an error
        if the reserved word abstract has been previously found.
        (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
        object renaming declaration with an access definition or subtype mark
        with a possible null exclusion.

        * par-ch9.adb: Minor error msg fix

        * par-load.adb: Add missing continuation mark to error msg

2006-10-31  Vincent Celier  <celier@adacore.com>

        * prj-dect.adb (Parse_Attribute_Declaration): Do not issue warning for
        unknown attribute in unknown package or in package that does not need
        to be checked.
        (Parse_Package_Declaration): Do not issue warning for unknown package in
        quiet output.

2006-10-31  Vincent Celier  <celier@adacore.com>

        Packages_To_Check.

2006-10-31  Vincent Celier  <celier@adacore.com>

        * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
        on VMS, change "__" to '.' before checking the name.
        (Record_Ada_Source): Always add the source file name in the list of
        of sources, even if it is not the first time, as it is for another
        source index.
        (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
        dot, instead of replacing only the first '_'.

        * prj-part.adb (Parse): Convert project file path to canonical form

        * prj-proc.adb (Recursive_Process): Make sure that, when a project is
        extended, the project id of the project extending it is recorded in its
        data, even when it has already been processed as an imported project.

2006-10-31  Robert Dewar  <dewar@adacore.com>

        * repinfo.adb (List_Entities): Don't list entities from renaming
        declarations.

            Robert Dewar  <dewar@adacore.com>

        * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
        only a restriction warning is active for the given restriction. This is
        desirable because we do not want to modify code in the case where only
        a warning is set.
        (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
        causes overriding of real restrictions.
        Take advantage of new No_Restrictions constant.

        * raise.h: (__gnat_set_globals): Change profile.

2006-10-31  Arnaud Charlet  <charlet@adacore.com>

        * rtsfind.adb: Remove s-polint from comment as it exists no more.

        * rtsfind.ads: 
        Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
        Move all the entities in obsolete package System.PolyORB_Interface to
        System.Partition_Interface.
        (RE_Storage_Size): New function in System.Tasking.
        (RE_Get_Ceiling): New entity.

        * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
        properly an attempt to apply Unchecked_Access to a protected operation.
        (OK_Self_Reference): New subprogram to check the legality of an access
        attribute whose prefix is the type of an enclosing aggregate.
        Generalizes previous mechanism to handle attribute references nested
        arbitrarily deep within the aggregate.
        (Analyze_Access_Attribute): An access attribute whose prefix is a type
        can appear in an aggregate if this is a default-initialized aggregate
        for a self-referential type.
        (Resolve_Attribute, case Access): Ditto.
        Add support for new implementation defined attribute Stub_Type.
        (Eval_Attribute, case Attribute_Stub_Type): New case.
        (Analyze_Attribute, case Attribute_Stub_Type): New case.
        (Stream_Attribute_Available): Implement using new subprogram from
        sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
        Has_Specified_Stream_Attribute flag.
        Disallow Storage_Size and Storage_Pool for access to subprogram
        (Resolve_Attribute, case 'Access et al): Take into account anonymous
        access types of return subtypes in extended return statements. Remove
        accessibility checks on anonymous access types when Unchecked_Access is
        used.
        (Analyze_Attribute): Add support for the use of 'Class to convert
        a class-wide interface to a tagged type.
        Add support for the attribute Priority.
        (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
        whether the designated type is discriminated with a constrained partial
        view and require static matching in that case.
        Add local variable Des_Btyp. The Designated_Type
        of an access to incomplete subtype is either its non-limited view if
        coming from a limited with or its etype if regular incomplete subtype.

        * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
        Fix predicate to identify and allow cases of (expander-generated)
        references to tag of designated object of a RACW.
        (Validate_Static_Object_Name): In Ada 2005, a formal object is
        non-static, and therefore cannot appear as a primary in a preelaborable
        package.
        (Has_Stream_Attribute_Definition): New subprogram, abstracted from
        Has_Read_Write_Attributes.
        (Has_Read_Write_Attributes): Reimplement in termes of
        Has_Stream_Attribute_Definition.
        (Missing_Read_Write_Attributes): When checking component types in a
        record, unconditionally call Missing_Read_Write_Attributes recursively
        (remove guard checking for Is_Record_Type / Is_Access_Type).

2006-10-31  Robert Dewar  <dewar@adacore.com>

        * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
        useless assignments here and conditionalize it on absence of exception
        handlers.
        (Analyze_Exception_Handlers): Small code reorganization of error
        detection code, for new handling of formal packages.

2006-10-31  Ed Schonberg  <schonberg@adacore.com>
            Hristian Kirtchev  <kirtchev@adacore.com>

        * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
        that has been constant-folded, preserve information of original tree,
        for ASIS uses.
        (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
        generated private extension declaration if the formal derived type is
        synchronized. Carry synchronized present over to the generated private
        extension.
        (Validate_Derived_Type_Instance): Ensure that the actual of a
        synchronized formal derived type is a synchronized tagged type.
        (Instantiate_Formal_Package): When creating the instantiation used to
        validate the actual package of a formal declared without a box, check
        whether the formal itself depends on a prior actual.
        (Instantiate_Formal_Subprogram): Create new entities for the defining
        identifiers of the formals in the renaming declaration, for ASIS use.
        (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
        a renaming declaration or a subtype declaration for an actual in an
        instance, capture location information of declaration in generic, for
        ASIS use.
        (Instantiate_Formal_Package): Add comments on needed additional tests.
        AI-317 (partial parametrization) is fully implemented.
        (Validate_Private_Type_Instance): Add check for actual which
        must have preelaborable initialization
        Use new // insertion for some continuation messages
        (Analyze_Formal_Object_Declaration): Change usage of Expression to
        Default_Expression. Add type retrieval when the declaration has an
        access definition. Update premature usage of incomplete type check.
        (Check_Access_Definition): New subsidiary routine. Check whether the
        current compilation version is Ada 05 and the supplied node has an
        access definition.
        (Instantiate object): Alphabetize local variables. Handle the creation
        of new renaming declarations with respect to the kind of definition
        used - either an access definition or a subtype mark. Guard against
        unnecessary error message in the context of anonymous access types after
        they have been resolved. Add check for required null exclusion in a
        formal object declaration.
        (Switch_View): A private subtype of a non-private type needs to be
        switched (the base type can have been switched without its private
        dependents because of the last branch of Check_Private_View.
        (Check_Private_View): Do not recompute Base_Type (T), instead use cached
        value from BT.
        (Instantiate_Type): Emit an error message whenever a class-wide type of
        a tagged incomplete type is used as a generic actual.
        (Find_Actual_Type): Extend routine to handle a component type in a child
        unit that is imported from a formal package in a parent.
        (Validate_Derived_Type_Instance): Check that analyzed formal and actual
        agree on constrainedness, rather than checking against ultimate ancestor
        (Instantiate_Subprogram_Body): Create a cross-reference link to the
        generic body, for navigation purposes.

            Thomas Quinot  <quinot@adacore.com>

        * sem_ch13.adb: Storage pool cannot be given for access to subprogram
        type.
        (New_Stream_Subprogram): When processing an attribute definition clause
        for a stream-oriented subprogram, record an entity node occurring at
        the point of clause to use for checking the visibility of the clause,
        as defined by 8.3(23) as amended by AI-195.
        (New_Stream_Subprogram): New procedure, factoring behaviour from both
         New_Stream_Function and New_Stream_Procedure.
        (New_Stream_Function, New_Stream_Procedure): Removed.
        (Analyze_Attribute_Definition_Clause, case Address): Check new

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

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

        * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
        procedure cannot be a protected operation (it is a basic_declaration,
        not a subprogram_declaration).
        (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
        Subp. Add logic for entry processing.
        (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
        Determine whether an entry or subprogram of a protected or task type
        override an inherited primitive of an implemented interface.
        (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
        Update the actual used in calls to Check_Overriding_Indicator.
        (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
        generate the proper reference to the parent unit, for cross-reference.
        (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
        Is_Formal.
        Add -gnatd.l --Use Ada 95 semantics for limited function returns,
        (Add_Extra_Formal): Revise procedure to allow passing in associated
        entity, scope, and name suffix, and handle setting of the new
        Extra_Formals field.
        (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
        pass new parameters. Add support for adding the new extra access formal
        for functions whose calls are treated as build-in-place.
        (Analyze_A_Return_Statement): Correct casing in error message.
        Move Pop_Scope to after Analyze_Function_Return, because an extended
        return statement really is a full-fledged scope. Otherwise, visibility
        doesn't work right. Correct use of "\" for continuation messages.
        (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
        evilly trying to call Analyze_Object_Declaration directly. Otherwise,
        the node doesn't get properly marked as analyzed.
        (Analyze_Subprogram_Body): If subprogram is a function that returns
        an anonymous access type that denotes a task, build a Master Entity
        for it.
        (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
        proper usage of null exclusion in a result definition.
        (Process_Formals): Code cleanup and new error message.
        (Process_Formals): Detect incorrect application of null exclusion to
        non-access types.
        (Conforming_Types): Handle conformance between [sub]types and itypes
         generated for entities that have null exclusions applied to them.
        (Maybe_Primitive_Operation): Add an additional type retrieval when the
         base type is an access subtype. This case arrises with null exclusions.
        (New_Overloaded_Entity): Do not remove the overriden entity from the
        homonym chain if it corresponds with an abstract interface primitive.
        (Process_Formals): Replace membership test agains Incomplete_Kind with a
        call to the synthesized predicate Is_Incomplete_Type.
        (Analyze_Subprogram_Body): Check wrong placement of abstract interface
        primitives.
        (Analyze_Subprogram_Declaration): Check that abstract interface
        primitives are abstract or null.
        (Analyze_Subprogram_Specification): Remove previous check for abstract
        interfaces because it was not complete.
        (Has_Interface_Formals): Removed.

        * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
        of Analyze_Package_Body, to create Itype references for anonymous
        access types created in the package declaration, whose designated types
        may have only a limited view.
        (Analyze_Package_Specification): For the private part of a nested
        package, install private_with_clauses of enclosing compilation unit if
        we are in its visible part.
        (Declare_Inherited_Private_Subprograms): Complete barrier
        to ensure that the primitive operation has an alias to some parent
        primitive. This is now required because, after the changes done for the
        implementation of abstract interfaces, the contents of the list of
        primitives has entities whose alias attribute references entities of
        such list of primitives.
        (Analyze_Package_Specification): Simplify code that handles parent units
        of instances and formal packages.
        (Uninstall_Declarations): Check the convention consistency among
        primitive overriding operations of a tagged record type.

        expected and found set right)
        (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
        (Analyze_Generic_Renaming): Same fix
        (Use_One_Package): Do not take into account the internal entities of
        abstract interfaces during the analysis of entities that are marked
        as potentially use-visible.
        (Find_Type): Handle the case of an attribute reference for
        implementation defined attribute Stub_Type (simply let the analysis of
        the attribute reference rewrite it).
        (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
        type that appears in a Use_Type clause.
        (Analyze_Object_Renaming): Add support for renaming of the Priority
        attribute.
        (Find_Type): In Ada 2005, a task type can be used within its own body,
        when it appears in an access definition.
        (Analyze_Object_Renaming): Remove warning on null_exclusion.
        (Analyze_Object_Renaming): Introduce checks for required null exclusion
         in a formal object declaration or in a subtype declaration.
        (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
        (Check_Null_Exclusion): New local routine to
        Analyze_Subprogram_Renaming. Check whether the formals and return
        profile of a renamed subprogram have required null exclusions when
        their counterparts of the renaming already impose them.
        (In_Generic_Scope): New local routine to Analyze_Object_Renaming.

        statements.
        (N_Extended_Return_Statement): New node for extended_return_statement

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

        Since we are changing the tree format anyway, also get rid of the

        (Tree_Read): Change the way of reading Tree_Version_String - now we
        read the version string from the tree even if its length is not the
        same as the length of the version string computed from Gnatvsn.

        (Freeze_Record_Type): Do not generate the tables associated with

        interfaces if compiling under No_Dispatching_Calls restriction.
        When compiling for Ada 2005, for a nonabstract
        type with a null extension, call Make_Controlling_Function_Wrappers
        and insert the wrapper function declarations and bodies (the latter
        being appended as freeze actions).
        (Predefined_Primitive_Bodies): Do not generate the bodies of the
        predefined primitives associated with timed and conditional

        service is available before generating a call.
        (Make_Controlling_Function_Wrappers): New procedure.
        (Expand_N_Full_Type_Declaration): Create a class-wide master for
        access-to-limited-interfaces because they can be used to reference
        tasks that implement such limited interface.
        (Build_Offset_To_Top_Functions): Build the tree corresponding to the
        procedure spec and body of the Offset_To_Top function that is generated
        when the parent of a type with discriminants has secondary dispatch
        tables.
        (Init_Secondary_Tags): Handle the case in which the parent of the type
        containing secondary dispatch tables has discriminants to generate the
        correct arguments to call Set_Offset_To_Top.
        (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.

        * a-tags.ads, a-tags.adb: (Check_Index): Removed.

        (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
        the same functionality of Get_Prim_Op_Address but applied to predefined
        primitive operations because the pointers to the predefined primitives
        are now saved in a separate table.
        (Parent_Size): Modified to get access to the separate table of primitive
        operations or the parent type.
        (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
        functionality of Set_Prim_Op_Address but applied to predefined primitive
        operations.
        (Set_Signature): New subprogram used to store the signature of a DT.
        (Displace): If the Offset_To_Top value is not static then call the
        function generated by the expander to get such value; otherwise use
        the value stored in the table of interfaces.
        (Offset_To_Top): The type of the actual has been changed to Address to
        give the correct support to tagged types with discriminants. In this
        case this value is stored just immediately after the tag field.
        (Set_Offset_To_Top): Two new formals have been added to indicate if the
        offset_to_top value is static and hence pass this value to the run-time
        to store it in the table of interfaces, or else if this value is dynamic
        and then pass to the run-time the address of a function that is
        generated by the expander to provide this value for each object of the
        type.

        in a subprogram are wrapped in a cleanup block, indicate that the
        subprogram contains an inner block with an exception handler.
        (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
        Adjust call is for a newly-allocated object. In that case we must not
        assume that the finalization list chain pointers are correct (since they
        come from a bit-for-bit copy of the original object's pointers) so if
        the attach level would otherwise be zero (no change), we set it to 4
        instead to cause the pointers to be reset to null.

        * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
        reset chain pointers to null.

        * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
        string, and the context requires a loop for the assignment (e.g.
        because the left-hand side is packed), generate a unique name for the
        temporary that holds the string, to prevent spurious name clashes.

        Update comments.
        (Expand_Call):  An indirect call through an access parameter of a
        protected operation is not a protected call.
        Add circuit to raise CE in Ada 2005 mode following call
        to Raise_Exception.
        (Register_DT_Entry): Do nothing if
        the run-time does not give support to abstract interfaces.
        (Freeze_Subprogram): In case of dispatching operations, do not generate
        code to register the operation in the dispatch table if the source
        is compiled with No_Dispatching_Calls.
        (Register_Predefined_DT_Entry): Generate code that calls the new
        run-time subprogram Set_Predefined_Prim_Op_Address instead of
        Set_Prim_Op_Address.

        * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
        on array assignments if the right-hand side is a function call that has
        been inlined. Check is performed on the assignment in the block.
        (Process_Bounds): If bounds and range are overloaded, apply preference
        rule for root operations to disambiguate, and diagnose true ambiguity.
        (Analyze_Assignment): Propagate the tag for a class-wide assignment with
        a tag-indeterminate right-hand side even when Expander_Active is True.
        Needed to ensure that dispatching calls to T'Input are allowed and
        get the tag of the target class-wide object.

        * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
        an inherited primitive operation that already overrides several
        abstract interface primitives. For transitivity, the new entity must
        also override all the abstract interface primitives covered by the
        inherited overriden primitive.
        Emit warning if new entity differs from homograph in same scope only in
        that one has an access parameter and the other one has a parameter of
        a general access type with the same designated type, at the same
        position in the signature.
        (Make_Inequality_Operator): Use source locations of parameters and
        subtype marks from corresponding equality operator when creating the
        tree structure for the implicit declaration of "/=". This does not
        change anything in behaviour except that the decoration of the
        components of the subtree created for "/=" allows ASIS to get the
        string images of the corresponding identifiers.
        (Analyze_Return_Statement): Remove '!' in warning message.
        (Check_Statement_Sequence): Likewise.
        (Analyze_Subprogram_Body): For an access parameter whose designated type
        is an incomplete type imported through a limited_with clause, use the
        type of the corresponding formal in the body.
        (Check_Returns): Implicit return in No_Return procedure now raises
        Program_Error with a compile time warning, instead of beging illegal.
        (Has_Single_Return):  Function returning unconstrained type cannot be
        inlined if expression in unique return statement is not an identifier.
        (Build_Body_To_Inline): It is possible to inline a function call that
        returns an unconstrained type if all return statements in the function
        return the same local variable. Subsidiary procedure Has_Single_Return
        verifies that the body conforms to this restriction.

        * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
        same type, and  one of them is of an anonymous access type, convert

        (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
        longer required to specify an vtable-ptr component in the record. For
        compatibility reasons we leave the support for the previous definition.
        (Analyze_Pragma, case No_Return): Allow multiple arguments

        * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
        non-overrideen inherited operation with a controlling result as
        illegal only its implicit declaration comes from the derived type
        declaration of its result's type.
        (Check_Possible_Deferred_Completion): Relocate the object definition
        node of the subtype indication of a deferred constant completion rather
        than directly analyzing it. The analysis of the generated subtype will
        correctly decorate the GNAT tree.
        (Record_Type_Declaration): Check whether this is a declaration for a
        limited derived record before analyzing components.
        (Analyze_Component_Declaration): Diagnose record types  not explicitly
        declared limited when a component has a limited type.
        (Build_Derived_Record_Type): Code reorganization to check if some of
        the inherited subprograms of a tagged type cover interface primitives.
        This check was missing in case of a full-type associated with a private
        type declaration.
        (Constant_Redeclaration): Check that the subtypes of the partial and the
        full view of a constrained deferred constant statically match.
        (Mentions_T): A reference to the current type in an anonymous access
        component declaration  must be an entity name.
        (Make_Incomplete_Type_Declaration): If type is tagged, set type of
        class_wide type to refer to full type, not to the incomplete one.
        (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
        available. Required to give support to the certified run-time.
        (Analyze_Component_Declaration): In case of anonymous access components
        perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
        (Process_Discriminants): For an access discriminant, use the
        discriminant specification as the associated_node_for_itype, to
        simplify accessibility checks.

            Javier Miranda  <miranda@adacore.com>

        * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
        abstract interpretations on an operator, remove interpretations that
        yield Address or a type derived from it, if one of the operands is an
        integer literal.
        (Try_Object_Operation.Try_Primitive_Operation,
        Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
        location when creating the new reference to a primitive or class-wide
        operation as a part of rewriting a subprogram call.
        (Try_Primitive_Operations): If context requires a function, collect all
        interpretations after the first match, because there may be primitive
        operations of the same type with the same profile and different return
        types. From code reading.
        (Try_Primitive_Operation): Use the node kind to choose the proper
        operation when a function and a procedure have the same parameter
        profile.
        (Complete_Object_Operation): If formal is an access parameter and prefix
        is an object, rewrite as an Access reference, to match signature of
        primitive operation.
        (Find_Equality_Type, Find_One_Interp): Handle properly equality given
        by an expanded name with prefix Standard, when the operands are of an
        anonymous access type.
        (Remove_Abstract_Operations): If the operation is abstract because it is
        inherited by a user-defined type derived from Address, remove it as
        well from the set of candidate interpretations of an overloaded node.
        (Analyze_Membership_Op): Membership test not applicable to cpp-class
        types.

2006-02-13  Bob Duff  <duff@adacore.com>

        * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
        redundant use clauses.
        In particular, if the scope of two use clauses overlaps, but one is not
        entirely included in the other, we should not warn.  This can happen
        with nested packages.
        (Analyze_Subprogram_Renaming): Protect the compiler against previously
        reported errors. The bug was reported when the compiler was built
        with assertions enabled.
        (Find_Type): If the node is a 'Class reference and the prefix is a
        synchronized type without a corresponding record, return the type
        itself.

2006-02-13  Javier Miranda  <miranda@adacore.com>

        * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
        if this is the full-declaration associated with a private declaration
        that implement interfaces, then the private type declaration must be
        limited.
        (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
        as aliased. The use of the 'access attribute is not available for such
        object (for this purpose the object should be explicitly marked as
        aliased, but being an anonymous type this is not possible).

        * sem_type.adb (Write_Overloads): Improve display of candidate
        interpretations.
        (Add_One_Interp): Do not add to the list of interpretations aliased
        entities corresponding with an abstract interface type that is an
        immediate ancestor of a tagged type; otherwise we have a dummy
        conflict between this entity and the aliased entity.
        (Disambiguate): The predefined equality on universal_access is not
        usable if there is a user-defined equality with the proper signature,
        declared in the same declarative part as the designated type.
        (Find_Unique_Type): The universal_access equality operator defined under
        AI-230 does not cover pool specific access types.
        (Covers): If one of the types is a generic actual subtype, check whether
        it matches the partial view of the other type.

        Integer'Value("- 5") and Integer'Value("-+5") now correctly
        raise Constraint_Error.

        Scan_Long_Long_Unsigned out into
        Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
        This prevents scanning leading blanks and sign twice.
        Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
        See RM-3.5(44).

        * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split

        in all the calls to Expand_Interface_Thunk. Instead of referencing the
        record component containing the tag of the secondary dispatch table we
        have to use the Offset_To_Top run-time function to get this information;
        otherwise if the pointer to the base of the object has been displace
        we get a wrong value if we use the 'position attribute.

        * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
        all the calls to Expand_Interface_Thunk.

        Get_Tagged_Kind and Set_Tagged_Kind.
        (Tagged_Kind): New function that determines the tagged kind of a type
        with respect to limitedness and concurrency and returns a reference to

        RE_TK_Tagged, RE_TK_Task.

        * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
        Init_Secondary_Tags_Internal to allow its use with interface types and
        also to generate the code for the new additional actual required
        by Set_Offset_To_Top.
        (Build_Init_Statements): In case of components associated with abstract
        interface types there is no need to generate a call to its IP.

        concurrent types.
        (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
        the bodies and specifications of the predefined primitive operations

        * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
        pointer initialization values. Make a SAVE_EXPR instead. Add comments
        about the use and expansion of SAVE_EXPRs in the various possible

        (Derived_Type_Declaration): If the parent of the full-view is an
        interface perform a transformation of the tree to ensure that it has
        the same parent than the partial-view. This simplifies the job of the
        expander in order to generate the correct object layout, and it is
        needed because the list of interfaces of the full-view can be given in
        any order.
        (Process_Full_View): The parent of the full-view does not need to be
        a descendant of the parent of the partial view if both parents are

        present in a list.
        (Find_Hidden_Interface): New function used to determine whether two
        lists of interfaces constitute a set equality. If not, the first
        differing interface is returned.
        (Process_Full_View): Improve the check for the "no hidden interface"
        rule as defined by AI-396.

        For ASIS tools, add the switches in package Compiler for
        the invocation of the compiler.

        * prj-attr.adb: Add package Check and its attributes

        * vms_conv.ads (Command_Type): New command Check, for gnatcheck

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

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

        SIZE and SIZE_UNIT which we need for later back-annotations.

        information, to resolve possible ambiguities in the instance.
        (Instance_Parent_Unit): New global variable to record the ultimate

        declarations of the parent scope the parent is still private, use its
        full view to construct the full declaration of the derived type.
        (Build_Derived_Record_Type): Relax the condition that controls the
        execution of the check that verifies that the partial view and
        the full view agree in the set of implemented interfaces. In
        addition, this test now only takes into account the progenitors.

        Descendant to Find_Ancestor_Interface to leave the code more clear.
        Remove wrong code that avoids the generation of an error message
        when the immediate ancestor of the partial view is an interface.
        In addition some minor reorganization of the code has been done to
        leave it more clear.
        (Analyze_Type_Declaration): If type has previous incomplete tagged

        instance as well.
        (Access_Type_Declaration): Clean up declaration of malformed type
        declared as an access to its own classwide type, to prevent cascaded
        crash.

        and derived protected types, the parent may be an interface that must
        be included in the interface list.
        (Access_Definition): If the designated type is an interface that may
        contain tasks, create Master_Id for it before analyzing the expression
        of the declaration, which may be an allocator.
        (Record_Type_Declaration): Set properly the interface kind, for use
        in allocators, the creation of master id's for task interfaces, etc.

        package associated with a generic instance or formal package, the
        private declarations of the parent must be installed (by calling new
        procedure Install_Parent_Private_Declarations).

        Handle properly a renaming_as_body generated for a stream operation
        whose default is abstract because the object type itself is abstract.
        (Find_Type): If the type is incomplete and appears as the prefix of a
        'Class reference, it is tagged, and its list of primitive operations
        must be initialized properly.
        (Chain_Use_Clauses): When chaining the use clauses that appear in the
        private declaration of a parent unit, prior to compiling the private
        part of a child unit, find on the scope stack the proper parent entity
        on which to link the use clause.

        conversions that have no effect in the generated code because no

        * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
        position set is provided, we compute one in order to reduce the maximum
        length of the keys.  This computation first selects a character
        position between 1 and the minimum length of the keys in order to
        avoid reducing one of the keys to an empty string.
        (Initialize, Compute): When the ratio V to K is too low, the algorithm
        does not converge. The initialization procedure now comes with a
        maximum number of iterations such that when exceeded, an exception is
        raised in Compute. The user can initialize this ratio to another value

        * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
        become local to the whole package.
        (Install_Limited_Withed_Unit): Instead of unchaining real entities if
        the package was already analyzed the new algorithm "replaces" the
        real entities by the shadow ones. This is required to ensure that
        the order of these entities in the homonym chains does not change;
        otherwise we can have undefined references at linking time because
        in case of conflicts the external name of the entities will have
        a suffix that depends on the order of the entities in the chain.
        (Remove_Limited_With_Clause): Complementary code that completes the
        new algorithm and replaces the shadow entities by the real ones.
        (Install_Limited_Withed_Unit): When unchaining entities before the
        installation of the shadow entities, only regular entities of the
        public part must be taken into account. This is required to
        keep this routine in synch with the work done by Remove_Limited_
        With_Clause
        (Install_Limited_With_Clause): Introduce implicit limited_with_clause
        even if unit is analyzed, because the analysis of the unit is
        idempotent in any case, and the limited view of the unit may have to
        be installed for proper visibility.
        (Expand_Limited_With_Clause): Even if the unit in the implicit
        with_clause has been analyzed already, a limited view of the package
        must be built for the current context, if it does not exist yet.

            Javier Miranda  <miranda@adacore.com>

        * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
        underlying type
        to check if a type is Constrained in cases related to code generation
        (rather than semantic checking) since otherwise we do not generate
        similar code for mutable private types depending if their
        discriminants are visible or not.
        (Check_Abstract_Overriding): Do not complain about failure to override
        the primitive operations used in dispatching selects since they will
        always be overriden at the freeze point of the type.
        (Access_Definition): Separate out handling for resetting the scope
        of an anonymous access function result type. Retrieve the scope
        of the associated function rather than using Current_Scope, which
        does not have a consistent value (depends on whether we're in the
        middle of analyzing formal parameters). Add ??? comment about
        finding a cleaner way to handle the special cases of scope setting.
        (Process_Incomplete_Dependents): A protected operation is never a
        dispatching operation (only its wrapper may be).
        (Build_Derived_Record_Type): In case of tagged private types that
        implement interfaces add derivation of predefined primitive
        operations.
        (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
        by two parameters that are used in case of derivation from abstract
        interface types: No_Predefined_Prims is used to avoid the derivation
        of predefined primitives from the interface, and Predefined
        Prims_Only is used to complete the derivation predefined primitives
        in case of private tagged types implementing interfaces.
        Fix typo in comments
        (Find_Interface_In_Descendant): Protect the frontend against
        wrong code with large circularity chains.
        (Is_Private_Overriding): Add support for entities overriding interface
        subprograms. The test failed because Entities associated with overriden
        interface subprograms are always marked as hidden (and used to build
        the secondary dispatch table); in this case the overriden entity is
        available through the field abstract_interface_alias (cf. override_
        dispatching_operation)
        (Access_Definition): Set the scope of the type to Current_Scope for the
        case of a function with an anonymous access result type.
        (Access_Subprogram_Declaration): Handle creation of the type entity for
        an access-to-function type with an anonymous access result.
        (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
        in handling for N_Access_Function_Definition.
        (Analyze_Subtype_Declaration): Modify the text of error message.
        (Derived_Type_Declaration): Modify the text of error message.

        (Analyze_Component_Declaration): Code cleanup.
        (Analyze_Object_Declaration): Code cleanup.
        (Analyze_Subtype_Declaration): Propagate the null-exclusion
        attribute in case of access types. Code cleanup.
        (Array_Type_Declaration): Code cleanup.
        (Process_Discriminants): Create the new null-excluding itype
        if required. Code cleanup.
        (Process_Subtype): Create the new null-excluding itype if
        required. Code cleanup.
        (Build_Derived_Record_Type): Code cleanup to avoid calling
        twice the subprogram derive_subprograms in case of private
        types that implement interfaces. In this particular case the
        subprogram Complete_Subprograms_Derivation already does the
        job associated with the second call.

        * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
        conversion to the full view when generating an operation for a
        discriminant whose type may currently be private.

            Javier Miranda  <miranda@adacore.com>

        * sem_ch4.adb (Transform_Object_Operation): In a context off the form
        V (Obj.F), the rewriting does not involve the indexed component, but
        only the selected component itself.
        Do not apply the transformation if the analyzed node is an actual of a
        call to another subprogram.
        (Complete_Object_Operation): Retain the entity of the
        dispatching operation in the selector of the rewritten node. The
        entity will be used in the expansion of dispatching selects.
        (Analyze_One_Call): Improve location of the error message associated
        with interface.
        (Analyze_Selected_Component): No need to resolve prefix when it is a
        function call, resolution is done when parent node is resolved, as
        usual.
        (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
        when attempting to resolve a call transformed from its object notation.
        (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
        of the argument list for each interpretation of the operation.
        (Try_Object_Operation): The designated type of an access parameter may
        be an incomplete type obtained through a limited_with clause, in which
        case the primitive operations of the type are retrieved from its full
        view.
        (Analyze_Call): If this is an indirect call, and the return type of the
        access_to_subprogram is incomplete, use its full view if available.

            Gary Dismukes  <dismukes@adacore.com>

        * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
        access types the null-exclusion and access-to-constant attributes must
        also match.
        (Analyze_Return_Statement): When the result type is an anonymous access
        type, apply a conversion of the return expression to the access type
        to ensure that appropriate accessibility checks are performed.
        (Analyze_Return_Type): For the case of an anonymous access result type,
        generate the Itype and set Is_Local_Anonymous_Access on the type.
        Add ??? placeholder for check to disallow returning a limited object
        in Ada 2005 unless it's an aggregate or a result of a function call.
        Change calls from Subtype_Mark to Result_Definition.
        (Analyze_Subprogram_Body): Change formal Subtype_Mark to
        Result_Definition in call to Make_Function_Specification.
        (Build_Body_To_Inline): Change Set_Subtype_Mark to
        Set_Result_Definition.
        (Make_Inequality_Operator): Change formal Subtype_Mark to
        Result_Definition in call to Make_Function_Specification.
        (Process_Formals): Create the new null-excluding itype if required.
        (New_Overloaded_Entity): For an entity overriding an interface primitive
        check if the entity also covers other abstract subprograms in the same
        scope. This is required to handle the general case, that is, overriding
        other interface primitives and overriding abstract subprograms inherited
        from some abstract ancestor type.
        (New_Overloaded_Entity): For an overriding entity that comes from
        source, note the operation that it overrides.
        (Check_Conformance, Type_Conformant): Addition of one new formal
        to skip controlling formals in the analysis. This is used to
        handle overloading of abstract interfaces.
        (Base_Types_Match): Add missing case for types imported from
        limited-with clauses
        (New_Overloaded_Entity): Add barrier to protect the use of
        the "alias" attribute.

        * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
        verify that the procedure and the entry are mode conformant.
        (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
        as a different operator, which is often a cut-and-paste error.

        * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
        used in controlling parameters exclude null because it is necessary to
        read the tag to dispatch, and null has no tag.
        (Override_Dispatching_Operation): If the previous operation is inherited
        from an interface, it becomes hidden  and does not participate in later
        name resolution.

            Gary Dismukes  <dismukes@adacore.com>

        * sem_res.adb (Resolve_Membership_Op): In case of the membership test
        "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
        the expander will generate the corresponding run-time check to evaluate
        the expression.
        (Resolve_Call): Check for legal type of procedure name or prefix that
        appears as a trigger in a triggering alternative.
        (Valid_Conversion): If expression is ambiguous and the context involves
        an extension of System, remove System.Address interpretations.
        (Resolve_Qualified_Expression): Reject the case of a specific-type
        qualification applied to a class-wide argument. Enhance comment
        to explain checking of Original_Node.
        (Resolve_Type_Conversion): The location of the error message was not
        general enough to handle the general case and hence it has been removed.
        In addition, this patch improves the text of the message.
        (Resolve_Type_Conversion): Add missing support for access to interface
        types.
        (Resolve_Type_Conversion): If the target is a class-wide interface type,
        do not expand if the expression is the actual in a call, because proper
        expansion will take place when the call itself is expanded.
        (Resolve_Allocator): If the context is an unchecked conversion, the
        allocator inherits its storage pool, if any, from the target type of
        the conversion.

        * sem_type.adb (Add_One_Interp): If a candidate operation is an
        inherited interface operation that has an implementation, use the
        implementation to avoid spurious ambiguities.
        (Interface_Present_In_Ancestor): In case of concurrent types we can't
        use the Corresponding_Record_Typ attribute to look for the interface
        because it is set by the expander (and hence it is not always
        available). For this reason we traverse the list of interfaces
        (available in the parent of the concurrent type).

        parameter.
        (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
        of an entry.
        (Safe_To_Capture_Value): A value (such as non_null) is not safe to
        capture if it is generated in the second operand of a short-circuit
        operation.
        Do not capture values for variables with address clauses.
        (Is_Object_Reference): Treat a function call as an object reference only
        if its type is not Standard_Void_Type.

            Arnaud Charlet  <charlet@adacore.com>

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

        * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
        Ada.Synchronous_Task_Control because there is no longer a need for a
        VxWorks specific version of this package. Target dependencies
        has been moved to System.Task_Primitives.Operations.

        * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
        longer needed.
        (InitializeCriticalSection, EnterCriticalSection,
        LeaveCriticalSection, DeleteCriticalSection): Replace the type
        pCriticalSection by an anonymous access type so that we avoid problems
        of accessibility to local objects.

        * s-taprop.ads, s-taprop-posix.adb, s-taprop-vxworks.adb,
        s-taprop-mingw.adb, s-taprop-vms.adb, s-taprop-solaris.adb,

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

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

        (Initialize_Interrupts): Removed, no longer used.

        * s-inmaop-posix.adb, s-inmaop-vms.adb, s-inmaop-dummy.adb,
        (Setup_Interrupt_Mask): New procedure.

        * s-intman-vxworks.ads, s-intman-vxworks.adb:  Update comments.

        * s-inmaop.ads (Setup_Interrupt_Mask): New procedure

        * s-interr.adb: Add explicit call to Setup_Interrupt_Mask now that
        this is no longer done in the body of s-taprop
        (Server_Task): Explicitely test for Pending_Action in case
        System.Parameters.No_Abort is True.

        * s-taasde.adb: Add explicit call to Setup_Interrupt_Mask now that this
        is no longer done in the body of s-taprop

        * exp_ch4.adb (Expand_Allocator_Expression): When an initialized
        allocator's designated type is a class-wide type, and compiling for
        Ada 2005, emit a run-time check that the accessibility level of the

        * exp_attr.adb (Expand_N_Attribute, case Attribute_Input): Generate
        call to Descendant_Tag rather than Internal_Tag.
        (Expand_N_Attribute, case Attribute_Output): Emit a check to ensure that

        (Make_Abstract_Interface_DT): Minor code cleanup.
        (Set_All_DT_Position): Code cleanup. As part of the code cleanup
        this subprogram implements a new algorithm that provides the
        same functionality and it is more clear in case of primitives
        associated with abstract interfaces.
        (Set_All_Interfaces_DTC_Entity): Removed. As part of the code
        clean up, the functionality of this subprogram is now provided
        by Set_All_DT_Position.

        within gdb to display the dispatch tables associated with a tagged
        type.

        the object to give access to the interface tag associated with the
        secondary dispatch table.
        (Expand_Interface_Thunk): New subprogram that generates the code of the
        thunk. This is required for compatibility with the C+ ABI.

        definition.
        (Complete_Subprograms_Derivation): New subprogram used to complete
        type derivation of private tagged types implementing interfaces.

        derivation if the derived type has an ancestor that is a formal type
        declared in the formal part of an enclosing generic.
        (Analyze_Object_Declaration): For protected objects, remove the check
        that they cannot contain interrupt handlers if not declared at library
        level.

        corresponding to all the abstract interface types implemented by a
        record type or a derived record type.

        we are in the case of an abstact-interface derivation
        (Find_Type_Of_Subtype_Indic): Moved from the body of the package
        to the specification because it is requied to analyze all the
        identifiers found in a list of interfaces

        * debug.adb: Complete documentation of flag "-gnatdZ"

        * exp_ch3.adb: Implement config version of persistent_bss pragma

        corresponding.
        (Component_Needs_Simple_Initialization): Similar to other tags,

        misaligned because of packing or representation clauses.
        (Is_Legal_Copy): New predicate to determine whether a possibly
        misaligned in-out actual can actually be passed by copy/return. This
        is an error in case the type is by_reference, and a warning if this is
        the consequence of a DEC import pragma on the subprogram.
        (Expand_Call, Freeze_Subprogram): Modified to give support to abstract
        interface types
        (Expand_Inlined_Call): Mark temporary generated for the return value as

        null procedure can always be inlined.
        (Expand_N_Subprogram_Declaration): If this is the declaration of a null
        procedure, generate an explicit empty body for it.

        * exp_util.ads, exp_util.adb (Find_Interface_ADT): New subprogram.

        is a predefined primitive operation.
        (Expand_Subtype_From_Expr): If the expression is a selected component

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

        we are compiling for a Configurable_Run_Time.
        (Instantiate_Formal_Subprogram): Indicate that null default subprogram
        If the program has a null default, generate an empty body for it.

        indicator is examined in Sem_Ch9 while analysing the subprogram
        declaration.
        (Check_Overriding_Indicator): Check consistency of overriding indicator
        on subprogram stubs as well.
        (Analyze_Subprogram_Declaration): Diagnose null procedures declared at
        the library level.
        (Analize_Subprogram_Specification): When analyzing a subprogram in which
        the type of the first formal is a concurrent type, replace this type
        by the corresponding record type.
        (Analyze_Subprogram_Body): Undo the previous work.
        (Analyze_Procedure_Call): If the call has the form Object.Op, the
        analysis of the prefix ends up analyzing the call itself, after which
        we are done.
        (Has_Interface_Formals): New subprogram subsidiary to analyze
        subprogram_specification that returns true if some non
        class-wide interface subprogram is found
        (New_Overloaded_Entity): Modified to give support to abstract
        interface types
        (Conforming_Types): In Ada 2005 mode, conformance checking of anonymous
        access to subprograms must be recursive.
        (Is_Unchecked_Conversion): Improve the test that recognizes
        instantiations of Unchecked_Conversion, and allows them in bodies that
        are to be inlined by the front-end. When the body comes from an
        instantiation, a reference to Unchecked_Conversion will be an
        Expanded_Name, even though the body has not been analyzed yet.
        Replace Is_Overriding and Not_Overriding in subprogram_indication with
        Must_Override and Must_Not_Override, to better express intent of AI.
        (Analyze_Subprogram_Body): If an overriding indicator is given, check

        at this point.
        (Analyze_Subprogram_Declaration): Indicate that a null procedure is
        always inlined.

        available through limited-with clauses.
        (Check_Dispatching_Operation): A stub acts like a body, and therefore is
        allowed as the last primitive of a tagged type if it has no previous
        spec.
        (Override_Dispatching_Operation, Check_Dispatching_Operation): Modified
        to give support to abstract interface types

        * sem_res.adb (Valid_Conversion): Perform an accessibility level check
        in the case where the target type is an anonymous access type of an
        object or component (that is, when Is_Local_Anonymous_Access is true).
        Prevent the special checks for conversions of access discriminants in
        the case where the discriminant belongs to a nonlimited type, since
        such discriminants have their accessibility level defined in the same
        way as a normal component of an anonymous access type.
        (Resolve_Allocator): When an allocator's designated type is a class-wide
        type, check that the accessibility level of type given in the

        types.
        (Valid_Tagged_Conversion): The conversion of a tagged type to an

        (Valid_Conversion): Modified to give support to abstract interface types
        (Resolve_Actuals): Enable full error reporting on view conversions
        between unrelated by_reference array types.
        The rule for view conversions of arrays with aliased components is
        weakened in Ada 2005.
        Call to obsolescent subprogram is now considered to be a violation of

        not statically match.

        * sem_ch5.adb (Analyze_Assignment): Replace the error messages on wrong
        null-exclusion value by a warning message

        defined for subprogram renaming declarations. When set, the field
        indicates the defining entity of a corresponding formal subprogram
        when the renaming corresponds to a formal subprogram association in an
        instantiation.
        (Set_Corresponding_Formal_Spec): New procedure to return
        Corresponding_Formal_Spec field.
        Minor changes of "=" to "in" in tests of N_Formal_Subprogram_Declaration

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

        dispatching, setting the controlling status of the formal parameters
        and result, and issuing an error if there is no controlling type for
        the formal subprogram.
        (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
        which is an unclean use of that field, we set the new field
        Corresponding_Formal_Spec to make the formal subprogram available to
        processing in Analyze_Subprogram_Declaration.
        (Analyze_Formal_{Discrete, Decimal_Fixed_Point, Fixed_Point,
        Floating_Point, Modular_Integer, Signed_Integer}_Type: Make formal type
        Constrained, so that it is is does not statically match its anonymous

        body for nested subprograms, before full analysis of said body.
        (Analyze_Subprogram_Body): Warn on inlining bodies with nested
        subprogram only if inner one comes from source.
        (Analyze_Function_Call): If the call is given in object notation, the
        analysis of the name rewrites the node and analyzes it with the proper
        argument list. After analyzing the name, if the call has been rewritten
        and the result type is set, no further analysis is needed.
        (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
        mark in function specification, in a context where the formals are
        visible and hide outer homographs.

        * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
        as the tagged type for the cases of abstract formal subprograms and

        * decl.c (maybe_pad_type): Use TYPE_SIZE_UNIT of the input type for
        TYPE_SIZE_UNIT of result type if SIZE is not specified.
        (make_aligning_type): Pass -1 as ADDRESSABLE to prevent the creation

        * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
        with an implicit dereference as its prefix, use
        Insert_Explicit_Dereference instead of merely rewriting the prefix into
        an explicit dereference. This ensures that a reference to the original
        prefix is generated, if appropriate.

        * sem_util.adb (Insert_Explicit_Dereference): When an implicit
        dereference is rewritten to an explicit one, generate a reference to
        the entity denoted by its prefix using the original prefix node, so
        the dereference can be properly recorded as a read of the denoted
        access value, if appropriate.

        * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
        emitting 'assigned but never read' warning on a variable on the basis
        that it has an access type.

        intrinsic

        * exp_intr.adb (Expand_Intrinsic_Call): Ignore unrecognized intrinsic,
        leaving call unchanged.
        This deals with the case where the pragma Import specified
        an external name, to be handled by the back end.

        * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
        subprogram which is Imported with convention Intrinsic if an

        for generation of DSA code targeted to the PolyORB PCS.
        (Add_Stub_Type): Rewrite to isolate the parts that are specific to one
        implementation of the partition communication subsystem in ancillary
        subprograms.
        (Specific_Build_Stub_Type, GARLIC_Support.Build_Stub_Type,

        and the Has_Pragma_Unreferenced flag for each formal before analyzing
        the body, to ensure that warnings are properly emitted for each accept
        statement of a given task entry.

        Prepend.
        (Remove_Next_Debug): Same fix

        * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do

        (Remove_Next): Same cleanup

2004-12-07  Thomas Quinot  <quinot@adacore.com>

        * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
        used to record an implicit dereference as a read operation on its
        prefix when operating under -gnatc. Necessary to avoid spurious
        'variable assigned but never read' warnings in that mode.
        (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
        is a non-overloaded implicit dereference, call the above subprogram to

        Make_Index.

2004-12-07  Ed Schonberg  <schonberg@adacore.com>

        * sem_ch8.adb (Find_Type): If node is a reference to 'Base and the

        * a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
        address of which may be used to represent "others" and "all others"
        choices in exception tables, instead of the current harcoded
        (void *)0 and (void *)1.
        (Setup_Exception): Do nothing in the GNAT SJLJ case.

        * gigi.h (others_decl, all_others_decl): New decls representing the
        new Others_Value and All_Others_Value objects.
        (struct attrib): Rename "arg" component as "args", since GCC expects a
        list of arguments in there.

        * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
        corresponding objects exported by a-exexpr, instead of hardcoded dummy
        addresses.

        * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
        others_decl and all_others_decl instead of hardcoded dummy addresses
        to represent "others" and "all others" choices, which is cleaner and
        more flexible with respect to the possible eh pointer encoding policies.

        * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
        (process_attributes): Account for the naming change of the "args"
        attribute list entry component.

        attributes for the current entity and propagate first subtype
        attributes to other subtypes.
        <E_Procedure>: Attribute arguments are attr->args and not
        attr->arg any more.
        (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
        argument provided, as this is what GCC expects. Use NULL_TREE instead
        of 0 for trees.

        replaced with calls to Get_Library_Unit_Name_String. Previously there
        were several instances of the same code in different locations in the
        compiler; this checkin completes the replacement of all of these
        instances with calls to a common subprogram.

        is more appropriately moved here. The cleanup involves making sure
        that the pragmas are properly attached to the tree, and that no
        nodes are improperly shared.

        * sem_prag.adb: Move expansion of Common_Object and Psect_Object

        string argument.

2004-11-18  Robert Dewar  <dewar@adacore.com>

        * errout.ads, errout.adb: (First_Sloc): New function

        * par-ch5.adb (P_Condition): Check for redundant parens is now a style
        check (-gnatyx) instead of being included as a redundant construct
        warning.

        * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
        Style_Check_Order_Subprograms.

        * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,

            Robert Dewar  <dewar@adacore.com>

        * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
        discriminant of a constrained subtype, analyze the copy of the
        corresponding constraint, because in some cases it may be only
        partially analyzed.
        Removes long-lived ??? comments.

        * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
        handled controlled or secondary-stack expressions within the
        iteration_scheme of a loop.

        * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
        bounds that may contain functions calls, to prevent memory leaks when
        the bound contains a call to a function that uses the secondary stack.
        (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
        generate temporaries for loop bounds that might contain function calls
        that require secondary stack and/or finalization actions.

        * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
        selected component and the selector is overloadable (not just a
        function) treat as function call, Analyze_Call will disambiguate if
        necessary.
        (Analyze_Selected_Component): Do not generate an actual subtype for the
        selected component if expansion is disabled. The actual subtype is only
        needed for constraint checks.
        (Analyze_Allocator): If restriction No_Streams is set, then do
        not permit objects to be declared of a stream type, or of a
        composite type containing a stream.

        * restrict.ads: Remove the a-stream entry from Unit_Array, since
        No_Streams no longer prohibits with'ing this package.

        * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
        discriminants, but the parent base has unknown discriminants, there is
        no discriminant constraint to inherit. Such a discrepancy can arise
        when the actual for a formal type with unknown discriminants is a
        similar private type whose full view has discriminants.
        (Analyze_Object_Declaration): If restriction No_Streams is set, then
        do not permit objects to be declared of a stream type, or of a
        composite type containing a stream.

        protected operations.

        * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
        generated name, it complicates decoding in gdb and hinders debugging
        of protected operations.
        (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
        flag for the protected entry barrier function.

        Works around the fact that gcc adds -fPIC by default under Darwin.

2004-11-18  Ed Schonberg  <schonberg@adacore.com>

        * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
        type of the object with the packed array type, set the Analyzed flag
        on the object if it is an entity or simple indexed component, to avoid
        spurious type errors.

        * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
        for Detect_Blocking which is redundant with the check done within the
        procedure Protected_Single_Entry_Call.
        (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
        Detect_Blocking which is redundant with the check done within the
        procedure Protected_Single_Entry_Call.

        * makegpr.adb (Compile): Put the compiling switches (in package
        Compiler and on the command line) immediately after "-c", instead of
        at the end of the command line invocation of the compiler, when
        compiling a non-Ada file.
        (Build_Global_Archive): When there is no need to rebuild the archive,
        set Global_Archive_Exists, so that the archive is passed to the linker
        if one is needed.

        Add documentation of new -gnatyx style check (check extra parens)
        Remove paragraph about gnatelim debug options.

        * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
        objects rather than forbidding dependencies on the package Ada.Streams.

        * sinfo.ads: Add ??? note that we should document pragmas passed to
        back end.

        Remove remaining pragma Import for C_Write
        Remove C_Read and C_Write from internal implementation unit
        GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
        the read and write functions from the system runtime library is fine
        on UNIX but won't work under Windows).

        * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
        (Check_Selector): Use C_Recv instead of C_Read.
        Selectors are the GNAT.Sockets abstraction to perform a select()
        call on a set of descriptors. To allow abortion of an ongoing
        select operation, some data is written to a dedicated socket that
        is always monitored.
        Under Windows, the write and read library functions cannot operate
        on sockets, so we need to use send and recv instead, which is portable
        across all supported platforms.

        * g-socthi.ads: Remove C_Read and C_Write from internal implementation
        unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
        (using the read and write functions from the system runtime library is
        fine on UNIX but won't work under Windows).

        The OS will adjust the size as needed.

        * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
        "__unix__" instead of "unix".
        The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
        sections were just mistakenly ignored. The former is
        implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
        Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
        of hpux. This prevents an unwanted definition of the symbol
        convert_addresses in adaint.o.

        (Expand_Array_Aggregate): An aggregate that initializes an allocator may
        be expandable in place even if the aggregate does not come from source.
        (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
        designated object of an allocator in place, rather than building it
        first on the stack. The previous scheme forces a full copy of the array,
        and may be altogether unsusable if the size of the array is too large
        for stack allocation.

        detect whether the call is in the right side of an assignment or
        the expression of an object declaration.  Recurse on component
        association within aggregates.
        Call it in the condition that determines whether the temporary is

        (DSA_Implementation_Name): This enumeration lists the possible
        implementations of the Partition Communication Subsystem for the
        Distributed Systems Annex (DSA). The three available implementations
        are the dummy stub implementation (No_DSA), and two versions based on
        two different distribution runtime libraries: GARLIC and PolyORB. Both
        the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
        technology.
        Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
        that organization.

        exception Prj.Prj_Error may be raised in case of problem.
        (Add_Unknown_Package, Add_Attribute): Moved to new child package
        Prj.Attr.PM.

        * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
        Protected_Action_Nesting.

        * s-taskin.ads: Adding the field Protected_Action_Nesting to the
        Common_ATCB record. It contains the dynamic level of protected action
        nesting for each task. It is needed for checking whether potentially
        blocking operations are called from protected operations.
        (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
        Detect_Blocking is active or not in the partition.

        * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,
        raise Program_Error if called from a protected operation.
        (Task_Entry_Call): When pragma Detect_Blocking is active, raise
        Program_Error if called from a protected operation.

        contains the required machinery for handling that.

        * sem_util.ads: Change comment associated to procedure
        Check_Potentially_Blocking_Operation.
        This procedure does not insert a call for raising the exception because
        that is currently done by the run time.

        * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.

        * init.c: Add the global variable __gl_detect_blocking that indicates
        whether pragma Detect_Blocking is active (1) or not (0). Needed for
        making the pragma available at run time.
        (__gnat_set_globals): Pass and update the detect_blocking parameter.

        DB is found in the ali file. Any unit compiled with pragma
        Detect_Blocking active forces its effect in the whole partition.

        * a-retide.adb (Delay_Until): Raise Program_Error if pragma
        Detect_Blocking is active and delay is called from a protected
        operation.

        * bindgen.adb (Gen_Adainit_Ada): When generating the call to
        __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma

        as Detect_Blocking parameter if pragma Detect_Blocking is active (0
        otherwise).

2004-09-09  Thomas Quinot  <quinot@act-europe.fr>

        * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
        GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash

        (Register_Receiving_Stub): Add Subp_Info formal parameter.
        Update API in placeholder implemetation of s-parint to reflect changes
        in distribution runtime library.

        * sem_ch3.adb (Expand_Derived_Record): Rename to
        Expand_Record_Extension.

        * sem_disp.adb (Check_Controlling_Formals): Improve error message for
        primitive operations of potentially distributed object types that have
        non-controlling anonymous access formals.

        * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
        subprogram.
        New implementation of expansion for remote access-to-subprogram types,
        based on the RACW infrastructure.
        This version of sem_dist is compatible with PolyORB/DSA as well as
        GLADE.

        * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
        Asynchrronous that applies to a remote access-to-subprogram type, mark
        the underlying RACW type as asynchronous.

        * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
         __gnat_using_gnu_linker to 1.

        * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
        g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
        GNAT.Perfect_Hash_Generators, and remove the empty
        GNAT.Perfect_Hash package.

        * atree.adb: Minor reformatting

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

        * exp_ch3.ads (Expand_Derived_Record): Rename to
        Expand_Record_Extension.

        * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.

        type.
        (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
        New subprograms. Used to create a proxy tagged object for a remote
        subprogram. The proxy object is used as the designated object
        for RAS values on the same partition (unless All_Calls_Remote applies).
        (Build_Get_Unique_RP_Call): New subprogram. Build a call to
        System.Partition_Interface.Get_Unique_Remote_Pointer.
        (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
        Renamed from Add_RAS_*_Attribute.
        (Add_Receiving_Stubs_To_Declarations): Generate a table of local
        subprograms.
        New implementation of expansion for remote access-to-subprogram types,
        based on the RACW infrastructure.

        * exp_dist.ads (Copy_Specification): Update comment to note that this
        function can copy the specification from either a subprogram
        specification or an access-to-subprogram type definition.

2004-09-09  Ed Schonberg  <schonberg@gnat.com>

        * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
        in an instance, between an explicit subprogram an one inherited from a
        type derived from an actual.

        * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
        add a polling call if the subprogram is to be inlined by the back-end,
        to avoid repeated calls with multiple inlinings.

        * checks.adb (Apply_Alignment_Check): If the expression in the address
        clause is a call whose name is not a static entity (e.g. a dispatching
        call), treat as dynamic.

2004-09-09  Robert Dewar  <dewar@gnat.com>

        * g-trasym.ads: Minor reformatting

        * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except
        packed arrays, since unused bits are expected to be zero for a
        comparison.

        it is an upward conversion of an untagged type with no representation
        change.

2004-09-01  Thomas Quinot  <quinot@act-europe.fr>

        * rtsfind.ads: Move RCI_Subp_Info and RCI_Subp_Info_Array to
        System.Partition_Interface.

        * checks.adb (Apply_Access_Checks): Do not generate checks when

2004-06-07  Thomas Quinot  <quinot@act-europe.fr>

        * bindgen.adb (Set_Unit_Number): Units is an instance of Table, and so
        the index of the last element is Units.Last, not Units.Table'Last
        (which is usually not a valid index within the actually allocated
        storage for the table).

        * exp_ch4.adb (Insert_Dereference_Action): Change predicate that

        source, or is the result of rewriting a dereference that comes from
        source.

2004-06-07  Romain Berrendonner  <berrendo@act-europe.fr>

        * bindgen.adb (Gen_Output_File): Add support for GAP builds.

2004-06-07  Eric Botcazou  <ebotcazou@act-europe.fr>

2004-06-07  Hristian Kirtchev  <kirtchev@gnat.com>

        * lib-xref.adb (Generate_Reference): Add nested function Is_On_LHS. It
        includes case of a variable referenced on the left hand side of an
        assignment, therefore remove redundant code. Variables and prefixes of
        indexed or selected components are now marked as referenced on left
        hand side. Warnings are now properly emitted when variables or prefixes
        are assigned but not read.

        * sem_warn.adb (Output_Unreferenced_Messages): Add additional checks to
        left hand side referenced variables. Private access types do not
        produce the warning "variable ... is assigned but never read".
        Add also additional checks to left hand side referenced variables.
        Aliased, renamed objects and access types do not produce the warning
        "variable ... is assigned but never read" since other entities may read
        the memory location.

2004-06-07  Jerome Guitton  <guitton@act-europe.fr>

        * sem_ch4.adb (Remove_Abstract_Operations): Refine the removal of
        predefined operators.
        Removes spurious type errors from g-trasym-vms.adb.

        * sem_res.adb (Rewrite_Renamed_Operator): If intrinsic operator is
        distinct from the operator appearing in the source, call appropriate
        routine to insert conversions when needed, and complete resolution of
        node.
        (Resolve_Intrinsic_Operator): Fix cut-and-paste bug on transfer of
        interpretations for rewritten right operand.
        (Set_Mixed_Mode_Operand): Handle properly a universal real operand when
        the other operand is overloaded and the context is a type conversion.

        * s-stchop.adsm s-stchop.adb, s-stchop-vxworks.adb: Remove the
        procedure Set_Stack_Size that is not needed.

        the case of multiple derivations.
        (Is_Object_Reference): For a selected component, verify that the prefix

        Same_Instantiated_Entity.
        (Same_Instantiated_Variable): Subsidiary to

        type.

        * exp_ch6.adb (Expand_N_Subprogram_Body): Use Is_Descendent_Of_Address
        to determine whether a subprogram should not be marked Pure, even when
        declared in a pure package.

2004-05-27  Jose Ruiz  <ruiz@act-europe.fr>

        * gnat_ugn.texi: Replace pragma Ravenscar by pragma Profile.

        * gnat_rm.texi: Replace Max_Entry_Queue_Depth by Max_Entry_Queue_Length
        Document No_Dynamic_Attachment, that supersedes No_Dynamic_Interrupts.
        Update the documentation about the Ravenscar profile, following the
        definition found in AI-249.

        * sem_prag.adb: Use FIFO_Within_Priorities and Ceiling_Locking when
        setting the Profile (Ravenscar). This must be done in addition to
        setting the required restrictions.

        * rtsfind.ads: Add the set of operations defined in package

        referenced.

2004-05-27  Geert Bosch  <bosch@gnat.com>

        * a-numaux-x86.adb (Reduce): Reimplement using an approximation of Pi
        with 192 bits of precision, sufficient to reduce a double-extended
        arguments X with a maximum relative error of T'Machine_Epsilon, for X
        in -2.0**32 .. 2.0**32.
        (Cos, Sin):  Always reduce arguments of 1/4 Pi or larger, to prevent
        reduction by the processor, which only uses a 68-bit approximation of
        Pi.
        (Tan): Always reduce arguments and compute function either using
        the processor's fptan instruction, or by dividing sin and cos as needed.

        (Remove_Limited_With_Clause): Update the implementation to undo the
        new work carried out by Build_Limited_Views.
        (Build_Chain): Complete documentation.
        Replace Ada0Y by Ada 0Y in comments
        Minor reformating

        * sem_ch3.adb (Array_Type_Declaration): In case of anonymous access

        subprogram we have to install the private_with clauses after its
        specification has been analyzed (as documented in AI-262.TXT).

        * sem_ch8.adb (Has_Private_With): New function. Determines if the
        current compilation unit has a private with on a given entity.
        (Find_Direct_Name): Detect the Beaujolais problem described in
        AI-262.TXT

        * sem_utils.ads, sem_util.adb (Is_Ancestor_Package): New function. It
        provides the functionality of the function Is_Ancestor that was
        previously available in sem_ch10. It has been renamed to avoid
        overloading.

2004-03-29  Ed Schonberg  <schonberg@gnat.com>

        * exp_ch6.adb (Expand_Call): A call to a function declared in the

        * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
        attribute reference does not denote a subtype, it can be any
        expression that has a classwide type, potentially after an implicit
        dereference.  In particular, the prefix can be a view conversion for
        a classwide type (for which Is_Object_Reference holds), but it can
        also be a value conversion for an access-to-classwide type. In the
        latter case, there is an implicit dereference, and the original node
        for the prefix does not verify Is_Object_Reference.

        * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
        conversion of a discriminant-dependent component of a mutable object
        is one itself.

        inherited, has convention C, and has unconstrained array parameters,
        place the corresponding warning on the derived type declaration rather
        than the original subprogram.

        * sem_ch12.adb (Instantiate_Formal_Subprogram): Set From_Default
        indication on renaming declaration, if formal has a box and actual
        is absent.

        * sem_ch8.adb (Analyze_Subprogram_Renaming): Use From_Default flag to
        determine whether to generate an implicit or explicit reference to
        the renamed entity.

        * sinfo.ads, sinfo.adb: New flag From_Default, to indicate that a
        subprogram renaming comes from a defaulted formal subprogram in an
        instance.

2004-03-25  Gary Dismukes  <dismukes@gnat.com>

        * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
        value expressions to ensure that calls within a component definition
        will be checked (since those are evaluated during the record type's
        elaboration).

        declaration for a child subprogram body that acts as a spec, indicate
        that the entity in the declaration needs debugging information.

        * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
        full view if the subtype is created for a constrained record component;
        gigi has enough information to construct the record, and there is no
        place in the tree for the declaration.

        * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
        serial number for the dummy body that is built for analysis, to avoid

        routine which will now be able to call the appropriate exception data
        accessor instead.

        * cstand.adb (Create_Standard): Adjust the type of the Import_Code
        component of Standard_Exception_Type to be the closest possible to
        Exception_Code in System.Standard_Library, that we cannot get at this
        point. Expand a ??? comment to notify that this type node should
        probably be rewritten later on.

        * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
        registration call to include a pointer to the exception object in the

        following -o, in canonical case, does not end with the executable
        suffix.  When in verbose mode and executable file name does not end
        with executable suffix, output the executable name, in canonical case.

        * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing

        priority in full, to ensure that any expanded subepxressions of it are

        after object declaration, skipping over code that may have been
        generated for validity checks.

        * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
        discriminants, ignore the known discriminants of its full view, if
        any, to check legality.

        * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained
        component if type has unknown discriminants.

        explicit dereference.
        (Expand_N_Slice): Same. Always do the rewriting, even for the case
        of non-packed slices, since the dereference action generated by
        expansion of the explicit dereference is needed in any case.
        (Expand_N_Selected_Component): When rewriting an implicit dereference,
        analyze and resolve the rewritten explicit dereference so it is seen
        by the expander.
        (Insert_Dereference_Action): This procedure is now called only for the
        expansion of an N_Explcit_Dereference_Node. Do insert a check even for
        dereferences that do not come from source (including explicit
        dereferences resulting from rewriting implicit ones), but do not
        recursively insert a check for the dereference nodes contained within

        Minor reformatting and code clean ups.
        Minor changes to prevent -gnatwa warnings

        * ali.adb: Minor reformatting and cleanup of code
        Acquire new SS indication of secondary stack use from ali files

        * a-numaux.ads: Add Pure_Function pragmas for all imported functions
        (since now we expect this to be done for imported functions)

        * bindgen.adb: Generate call to modify default secondary stack size if
        -Dnnn switch given

        * bindusg.adb: Add line for new -D switch

        * exp_aggr.adb (Type_May_Have_Bit_Aligned_Components): More appropriate
        replacement name for Type_May_Have_Non_Bit_Aligned_Components!
        Add circuitry for both records and arrays to avoid gigi
        processing if the type involved has non-bit-aligned components

        * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
        N_String_Literal node always references an E_String_Literal_Subtype
        entity. This may not be true in the future.
        (Possible_Bit_Aligned_Component): Move processing of
        Component_May_Be_Bit_Aligned from exp_ch5 to exp_util

        * exp_ch6.adb (Expand_Thread_Body): Pick up
        Default_Secondary_Stack_Size as variable so that we get value modified
        by possible -Dnnn binder parameter.

        * exp_util.adb (Component_May_Be_Bit_Aligned): New function.
        (Type_May_Have_Bit_Aligned_Components): New function.

        * exp_util.ads (Component_May_Be_Bit_Aligned): New function.
        (Type_May_Have_Bit_Aligned_Components): New function.

        * fe.h: (Set_Identifier_Casing): Fix prototype.
        Add declaration for Sem_Elim.Eliminate_Error_Msg.
        Minor reformatting.

        * freeze.adb (Freeze_Entity): Add RM reference to error message about
        importing constant atomic/volatile objects.
        (Freeze_Subprogram): Reset Is_Pure indication for imported subprogram
        unless explicit Pure_Function pragma given, to avoid insidious bug of
        call to non-pure imported function getting eliminated.

        * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb,
        gnatls.adb, gnatlink.adb, gnatmem.adb, gnatname.adb, gnatsym.adb,
        gnatxref.adb, gprcmd.adb, gprep.adb, make.adb: Minor reformatting
        Add 2004 to printed copyright notice

        * lib-writ.ads, lib-writ.adb: Put new SS flag in ali file if secondary
        stack used.

        * Makefile.rtl: Add entry for g-sestin.o

        New switch Sec_Stack_Used (GNAT, GNATBIND)
        Make Default_Secondary_Stack_Size a variable instead of a constant,
        so that it can be modified by the new -Dnnn bind switch.

        * rtsfind.adb (Load_Fail): Give full error message in configurable
        run-time mode if all_errors mode is set. This was not done in the case
        of a file not found, which was an oversight.
        Note if secondary stack unit is used by compiler.

        * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
        ineffective elaborate all pragmas on non-visible packages (this
        happened when a renamed subprogram was called). Now the elaborate all
        always goes on the package containing the renaming rather than the one
        containing the renamed subprogram.

        * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
        (Process_Eliminate_Pragma): Add parameter to capture pragma location.

        * sem_eval.adb (Eval_String_Literal): Do not assume that string literal
        has an Etype that references an E_String_Literal.
        (Eval_String_Literal): Avoid assumption that N_String_Literal node
        always references an E_String_Literal_Subtype entity. This may not
        be true in the future.

        * sem_prag.adb (Process_Eliminate_Pragma): Add parameter to capture
        pragma location.

        * sem_res.adb (Resolve): Specialize msg for function name used in proc
        call.

2004-01-05  Ed Falis  <falis@gnat.com>

        form.

2004-01-05  Vincent Celier  <celier@gnat.com>

        * bld.adb: Minor comment updates
        (Process_Declarative_Items): Correct incorrect name (Index_Name instead
        of Item_Name).

        * make.adb (Gnatmake): Special process for files to compile/check when
        -B is specified. Fail when there are only foreign mains in attribute
        Main of the project file and -B is not specified. Do not skip bind/link
        steps when -B is specified.

        * makeusg.adb: Document new switch -B

        * opt.ads (Build_Bind_And_Link_Full_Project): New Boolean flag

        * trans.c (tree_transform, case N_Free_Statement): Handle thin pointer
        case.

        * misc.c (gnat_printable_name): If VERBOSITY is 2, call
        Set_Identifier_Casing.

        * decl.c (gnat_to_gnu_entity, E_Function): Give error if return type
        has size that overflows.

2004-01-05  Gary Dismukes  <dismukes@gnat.com>

        * exp_ch4.adb (Expand_Array_Comparison): Add Boolean constant to avoid
        -gnatwa warning on static condition.

2004-01-05  Doug Rupp  <rupp@gnat.com>

        * link.c: (shared_libgnat_default) [VMS]: Change to STATIC.

        library naming scheme.

        * mlib-prj.adb (Build_Library): Generate different names for the static
        or dynamic version of the GNAT runtime. This is needed to support the
        new shared library naming scheme.
        (Process_Binder_File): Add detection of shared library in binder file
        based on the new naming scheme.

        * gnatlink.adb (Process_Binder_File): Properly detect the new naming
        scheme for the shared runtime libraries.

        * Makefile.in:
        (LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
        scheme.
        (install-gnatlib): Do not create symlinks for shared libraries.
        (gnatlib-shared-default): Idem.
        (gnatlib-shared-dual-win32): New target. Not used for now as the
        auto-import feature does not support arrays/records.
        (gnatlib-shared-win32): Do not create copy for the shared libraries.
        (gnatlib-shared-vms): Fix shared runtime libraries names.

        * osint.ads, osint.adb (Shared_Lib): New routine, returns the target
        dependent runtime shared library name.

2004-01-05  Vasiliy Fofanov  <fofanov@act-europe.fr>

        * osint.adb (Read_Library_Info): Remove bogus check if ALI is older
        than the object.

2004-01-05  Ed Schonberg  <schonberg@gnat.com>

        * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
        protected objects when allocator has a subtype indication, not a
        qualified expression. Note that qualified expressions may have to be
        checked when limited aggregates are implemented.

        * sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
        pure, emit warning.
        (Analyze_Pragma, case Pure_Function): If enclosing package is pure and
        subprogram is imported, remove warning.

        the other standard types).

2003-12-17  Robert Dewar  <dewar@gnat.com>

        * s-crtl.ads: Fix header format

        the expression type only if it is declared in the current unit.

        * sem_ch3.adb (Constrain_Index): Handle properly a range whose bounds
        are universal and already analyzed, as can occur in constrained
        subcomponents that depend on discriminants, when one constraint is a
        subtype mark.

        * sem_res.adb (Resolve_Type_Conversion): Any arithmetic expression of
        type Any_Fixed is legal as the argument of a conversion, if only one
        fixed-point type is in context.

2003-12-17  GNAT Script  <nobody@gnat.com>

        * init.c:
        Created and exported __gnat_map_signal to support signal -> exception
        mapping that is dependent on the VxWorks version.

        * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
        bounds of a loop, create a separate block in order to generate proper
        cleanup actions to prevent memory leaks.

        * sem_res.adb (Resolve_Call): After a call to
        Establish_Transient_Scope, the call may be rewritten and relocated, in
        which case no further processing is needed.

        * sem_util.adb: (Wrong_Type): Refine previous fix.
         Fixes ACATS regressions.

        PR ada/13353

        obsolete files.

        * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
        (rts-zfp): Ditto.

2003-12-08  Robert Dewar  <dewar@gnat.com>

        * 7sintman.adb: Minor reformatting

        * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
        standard linker options to get standard libraries linked. We now plan
        to provide dummy versions of these libraries to match the appropriate
        configurable run-time (e.g. if a library is not needed at all, provide
        a dummy empty library).

        * targparm.ads: Configurable_Run_Time mode no longer affects linker
        options (-L parameters and standard libraries). What we plan to do is
        to provide dummy libraries where the libraries are not required.

        * gnatbind.adb: Minor comment improvement

2003-12-08  Javier Miranda  <miranda@gnat.com>

        * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
        aggregate in the parent. Otherwise constants with limited aggregates
        are not supported. Add new formal to pass the component type (Ctype).
        It is required to call the corresponding IP subprogram in case of
        default initialized components.
        (Gen_Assign): In case of default-initialized component, generate a
        call to the IP subprogram associated with the component.
        (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
        of aggregate with default initialized components.
        (Has_Default_Init_Comps): Improve implementation to recursively check
        all the present expressions.

        * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
        to indicate that the initialization call corresponds to a
        default-initialized component of an aggregate.
        In case of default initialized aggregate with tasks this parameter is
        used to generate a null string (this is just a workaround that must be
        improved later). In case of discriminants, this parameter is used to
        generate a selected component node that gives access to the discriminant
        value.

        * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
        subprogram, based on Build_Task_Allocate_Block, but adapted to expand
        allocated aggregates with default-initialized components.

        * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
        the box notation is used in positional aggregates.

        Set the scanner to return ends of line and comments as tokens, if
        Store_Comments is True.
        (Pre_Parse_Context_Clause): Create the N_With_Clause nodes so that
        comments are associated with these nodes. Store the node IDs in the
        With_Records.
        (Post_Parse_Context_Clause): Use the N_With_Clause nodes stored in the
        With_Records.
        (Parse_Single_Project): Call Pre_Parse_Context_Clause before creating
        the N_Project node. Call Tree.Save and Tree.Reset before scanning the
        current project. Call Tree.Restore afterwards. Set the various nodes
        for comment storage (Next_End, End_Of_Line, Previous_Line,
        Previous_End).

        * prj-part.ads (Parse): New Boolean parameter Store_Comments,
        defaulted to False.

        * prj-pp.adb (Write_String): New Boolean parameter Truncated, defaulted

        (Print): Process comments for nodes N_With_Clause,
        N_Package_Declaration, N_String_Type_Declaration,
        N_Attribute_Declaration, N_Typed_Variable_Declaration,
        N_Variable_Declaration, N_Case_Construction, N_Case_Item.
        Process nodes N_Comment.

        * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
        without comments and there are some comments, set the flag
        Unkept_Comments to True.
        (Scan): If there are comments, set the flag Unkept_Comments to True and
        clear the comments.

        to link.

2002-02-07  Richard Henderson  <rth@redhat.com>

        * adaint.c (__gnat_to_gm_time): First arg is int, not time_t.

2002-01-30  Richard Henderson  <rth@redhat.com>

        * trans.c (tree_transform) [N_Loop_Statement]: Use
        expand_exit_loop_top_cond.

        rule which was mandated by code generation issues.

        * gnat-style.texi (header): Add @dircategory, @direntry.
        (title page): Remove date.
        (general) Add @./@: where approriate, and two spaces after the
        full stop at the end of a sentence.  Use @samp markup when
        referring concrete lexical entities (keywords, attribute names
        etc.), and @syntax for ARM grammar elements. Use @r for English
        text in comments.  Use @emph for emphasis.  Change "if-statements"

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

2001-12-19  Olivier Hainque <hainque@gnat.com>

        * raise.c (__gnat_eh_personality): Exception handling personality
        routine for Ada.  Still in rough state, inspired from the C++ version
        and still containing a bunch of debugging artifacts.

2001-12-19  Robert Dewar <dewar@gnat.com>

        * a-ngelfu.adb: Remove ??? comment for inappropriate Inline_Always
        Add 2001 to copyright date

        * g-regpat.adb: Change pragma Inline_Always to Inline. There is no
        need to force universal inlining for these cases.

2001-12-19  Arnaud Charlet <charlet@gnat.com>

        * s-taprob.adb: Minor clean ups so that this unit can be used in
        Ravenscar HI.

        discriminant check if the selected component is a component of
        the argument of an initialization procedure.

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

2001-12-17  Robert Dewar <dewar@gnat.com>

        * sem_res.adb: Minor reformatting

        * trans.c (tree_transform, case N_Real_Literal): Add missing third

        e.g. for the Ada personality routine when the GCC 3 mechanism is used.
        (Propagate_Exception, Raise_Current_Excep, Raise_From_Signal_Handler):
        Use the new notification routines.

2001-12-17  Emmanuel Briot <briot@gnat.com>

        * prj-tree.ads (First_Choice_Of): Document the when others case

2001-12-17  Arnaud Charlet <charlet@gnat.com>

        * bindgen.adb (Gen_Ada_Init_*): Set priority of environment task in
        HI-E mode, in order to support Ravenscar profile properly.

        * cstand.adb (Create_Standard): Duration is a 32 bit type in HI-E
        mode on 32 bits targets.

        (Time_Stamp_Mismatch): use CRC_Match for comparison.
        (Set_Source_Table): idem.

        * ali-util.ads:
        (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
        instead of simple checksum.
        (CRC_Match): new function.
        (CRC_Error): new constant.

        * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
        a CRC now and not a simple checksum. A CRC uses lower-case hex
        letters, fixes ambiguity in parsing.

        * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
        is what this variable will store.

        * bcheck.adb: Change reference to chechsum in comments by CRC.
        (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
        rename All_Checksum_Match to All_CRC_Match. Change due to API
        renaming since now GNAT does not use a simple checksum but a
        CRC using GNAT.CRC32.

        * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
        now and not anymore a simple checksum.

        * lib-load.adb: Use Source_CRC instead of Source_Checksum in many
        places.

        * lib-writ.adb (Write_ALI): Use Source_CRC instead of Source_Checksum.

        * scans.adb:
        (Restore_Scan_State): rename Checksum to CRC.
        (Save_Scan_State): idem.

        * scans.ads:
        With GNAT.CRC32.
        (Checksum): rename to CRC.
        (Saved_Scan_State): Save_Checksum field renamed to Save_CRC

        * scn-nlit.adb: Rename many Accumulate_Checksum to Update (from
        GNAT.CRC32).  Update copyright notice.

        * scn-slit.adb: Rename many Accumulate_Checksum to Update (from
        GNAT.CRC32).  Update copyright notice.

        * scn.adb:
        (Accumulate_Checksum): removed.
        (Update): new procedure. Add a wide-character into the CRC.

        * sinput-l.adb:
        (Complete_Source_File_Entry): use CRC32 instead of simple checksum.
        (Load_File): fix initialization of S (change Source_Checksum to
        Source_CRC)

        * sinput-p.adb (Load_Project_File): rename Source_Checksum to
        Source_CRC in S initialization.

        * sinput.adb (Source_Checksum): renamed to Source_CRC.

        * sinput.ads (Source_Checksum): renamed to Source_CRC.
        Update comments for the CRC.

        * types.adb (Hex): Use lowercase for the letter part.

        * types.ads (Get_Hex_String): Returns the hexadecimal representation
        for a word. This is currently used only for CRC. In previous version,
        the checksum was using a representation with all letter being
        upper-case. With the new implementation (using CRC) we do not remove
        the 32th bit of the CRC, so we can have an upper-case starting letter
        in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
        It is ambigous since the CRC was optional and could be followed by
        options like EB, EE. So now this routines uses lower-case letter for
        the hexadecimal representation. Strange enough only lower case letters
        where checked in Scan_ALI (even if this was not a possible case).

        * gnatvsn.ads (Library_Version): changed to 3.15a.

        * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
        for the compiler.

        * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
        for the compiler.

        * ali-util.adb: Redo previous change to avoid using word CRC everywhere
        Add 2001 to copyright notice
        (Accumulate_Checksum): Modify to use System.CRC32.

        * ali-util.ads: Redo changes of previous revision to continue to use
        the word Checksum. Add 2001 to copyright notice.

        * ali.adb: Undo some of previous changes, not needed.
