        * a-taster.ads, a-taster.adb: New files.
 
        * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
        link to the version that does nothing. This way the task termination
        routine is not executed twice for the environment task when finishing
        because of an unhandled exception.
 
        * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
        handler because of an unhandled exception.
 
        * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
        System.Tasking.Utilities instead of that in System.Tasking.Stages.
 
        * s-finimp.adb (initialization code): Modify the soft link for the
        finalization of the global list instead of Adafinal.
 
        * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
        non-tasking version of the soft link for task termination. We do
        nothing since if we are using the non-tasking version it
        means that the task termination functionality is not used.
        (Null_Finalize_Global_List): Add this null version for the procedure
        in charge of finalizing the global list for controlled objects.
        (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
        instead for handling run-time termination in a more flexible way.
        (Adafinal_NT): This new procedure will take care of finalizing the
        global list for controlled objects if needed, but no tasking
        finalization.
 
        * s-tarest.adb (Task_Lock): Do not try to lock again the
        Global_Task_Lock if we already own it. Otherwise, we get blocked in
        some run-time operations.
        (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
        until all nested locks have been released.
        (Task_Wrapper): Call the fall-back task termination handler. It
        applies to all tasks but the environment task.
        (Finalize_Global_Tasks): Add the call for the task termination
        procedure for the environment task.
        (Task_Wrapper): suppress warnings around declaration of
        Secondary_Stack_Address.
 
        * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
        moved to the Common_ATCB record.
        (Task_Lock): Global_Task_Lock_Nesting has been moved to the
        Common_ATCB record.
        (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
        Common_ATCB record.
 
        * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
        Fall_Back_Handler, and Specific_Handler.
 
        * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
        defined in Ada.Task_Termination, to avoid circular dependencies.
        (Termination_Handler): Redefine this type here, alredy defined in
        Ada.Task_Termination, for avoiding circular dependencies.
        (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
        for storing task termination handlers. In addition,
        Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
        Common_ATCB because it is used by both the regular and the restricted
        run times.
        (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
        Common_ATCB because it is used by both the regular and the restricted
        run times.
        (Common_ATCB): Added a dynamic task analyzer field.
 
        * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
        potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
        (Task_Wrapper): Call the task termination handler. It applies to all
        tasks but the environment task.
        (Finalize_Global_Tasks): Call the task termination procedure for the
        environment task. The call to Finalize_Global_List is now performed
        using the soft links mechanism.
        (Task_Wrapper): added dynamic stack analysis.
 
        * s-tasuti.adb (Abort_Tasks): The code in charge of checking
        potentially blocking operations has been moved from
        System.Tasking.Stages.Abort_Tasks to this procedure. There can be
        direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
        through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
        this run-time check.
 
        * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
        of task termination procedure.
        (Init_Tasking_Soft_Links): Install the task-safe version of the soft
        link for the task termination procedure.

        (Put): now uses the value of Current_Out to know if the output has to be
        send to stderr or stdout.
 
        * s-stausa.ads: Complete implementation.
 
        * switch-b.adb: Added handling of -u switch for dynamic stack analysis.
 
        * impunit.adb (Non_Imp_File_Names_05): Add Ada.Task_Termination to the
        list of Ada 05 files.
        (GNAT Library Units): Add AltiVec files.

2005-12-09  Javier Miranda  
            Hristian Kirtchev  
 
        * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
        to the specification because the frontend generates code that uses this
        subprogram.
        (Set_Interface_Table): Add missing assertion.
        Update documentation describing the run-time structure.
        (Displace): New subprogram that displaces the pointer to the object
        to reference one of its secondary dispatch tables.
        (IW_Membership): Modified to use the new table of interfaces.
        (Inherit_TSD): Modified to use the new table of interfaces.
        (Register_Interface_Tag): Use the additional formal to fill the
        contents of the new table of interfaces.
        (Set_Interface_Table): New subprogram that stores in the TSD the
        pointer to the table of interfaces.
        (Set_Offset_To_Top): Use the additional formal to save copy of
        the offset value in the table of interfaces.

        conversion.
        (Get_Tagged_Kind, Set_Tagged_Kind): New bodies.
 
        * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
        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.
        (Make_Secondary_DT): Secondary dispatch tables do not have a table of
        interfaces; hence the call to Set_Interface_Table was clearly wrong.
        (Collect_All_Interfaces): Modify the internal subprogram Collect to
        ensure that the interfaces implemented by the ancestors are placed
        at the header of the generated list.
        (Expand_Interface_Conversion): Handle the case in which the displacement
        associated with the interface conversion is not statically known. In
        this case we generate a call to the new run-time subprogram Displace.
        (Make_DT): Generate and fill the new table of interfaces.
        (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
        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_Tagged_Kind.
        (Make_Disp_Asynchronous_Select_Body, Make_Disp_Conditional_Select_Body,
        Make_Disp_Timed_Select_Body): Correctly retrieve the pointer to the
        primary dispatch table for a type.
        (Make_DT, Make_Secondary_DT): Set the tagged kind in the primary and
        secondary dispatch table respectively of a tagged type.
 
        * exp_disp.ads (Expand_Interface_Thunk): Remove Thunk_Id formal.
        (Expand_Interface_Conversion): New subprogram to indicate if the
        displacement of the type conversion is statically known.
        (DT_Access_Action): Add values Get_Tagged_Kind and Set_Tagged_Kind.
 
        * rtsfind.ads (RE_Offset_To_Top): New entity
        (RTU_Id): Add Ada_Task_Termination to the list so that it is made
        accessible to users.
        (Re_Displace): New entity
        (RE_Interface_Data): New entity
        (RE_Set_Interface_Data): New_Entity
        (RE_Id, RE_Unit_Table): Add entry for RE_Get_Tagged_Kind,
        Set_Tagged_Kind, RE_Tagged_Kind, RE_TK_Abstract_Limited_Tagged,
        RE_TK_Abstract_Tagged, RE_TK_Limited_Tagged, RE_TK_Protected,
        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.
        (Freeze_Record_Type): Generate Select Specific Data tables only for
        concurrent types.
        (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
        the bodies and specifications of the predefined primitive operations
        dealing with dispatching selects and abort, 'Callable, 'Terminated only
        for concurrent types.
 
        * exp_sel.ads, exp_sel.adb: New files.

        Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
        properly protected objects and attach handler in the case of the
        restricted profile.
        Move embeded package Select_Expansion_Utilities into a separate external
        package.
        (Expand_N_Asynchronous_Select, Expand_N_Conditional_Select,
        Expand_N_Timed_Entry_Call): Correct calls external package Exp_Sel.
        (Build_K, Build_S_Assignment): New subprograms, part of the select
        expansion utilities.
        (Expand_N_Asynchronous_Select, Expand_N_Conditional_Entry_Call,
        Expand_N_Timed_Entry_Call): Optimize expansion of select statements
        where the trigger is a dispatching procedure of a limited tagged type.
 
2005-12-09  Olivier Hainque  
 
        * 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

        source line information than what the current global locus indicates
        when appropriate.
 
        * utils2.c (build_simple_component_ref): Return 0 if the offset of the

        we are not defining the type.
        : Likewise.
        (gnat_to_gnu_entity) : Adjust comments and structure
        to get advantage of the new maybe_stabilize_reference interface, to
        ensure that what we reference is indeed stabilized instead of relying
        on assumptions on what the stabilizer does.
        (gnat_to_gnu_entity) : If the entity is an incomplete
        type imported through a limited_with clause, use its non-limited view.
        (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
        differentiation.
        (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix

        before early-returning for certain types when code generation is
        disabled.
        (gnat_to_gnu_entity) : Adjust comment attached to the
        nullification of gnu_expr we do for objects with address clause and
        that we are not defining.
        (elaborate_expression_1): Do not create constants when creating
        variables needed by the debug info: the dwarf2 writer considers that
        CONST_DECLs is used only to represent enumeration constants, and emits
        nothing for them.
        (gnat_to_gnu_entity) : When turning a non-definition of an
        object with an address clause into an indirect reference, drop the
        initializing expression.
        Include "expr.h".
        (STACK_CHECK_BUILTIN): Delete.

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

        check for a potential violation of a No_Elaboration_Code restriction.
        (maybe_stabilize_reference): New function, like gnat_stabilize_reference
        with extra arguments to control whether to recurse through non-values
        and to let the caller know if the stabilization has succeeded.
        (gnat_stabilize_reference): Now a simple wrapper around
        maybe_stabilize, for common uses without restriction on lvalues and
        without need to check for the success indication.
        (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
        pass false instead of 0 as the FORCE argument which is a bool.
        (Identifier_to_gnu): Remove checks ensuring that an renamed object
        attached to a renaming pointer has been properly stabilized, as no such
        object is attached otherwise.
        (call_to_gnu): Invoke create_var_decl to create the temporary when the
        function uses the "target pointer" return mechanism.
        Reinstate conversion of the actual to the type of the formal
        parameter before any other specific treatment based on the passing
        mechanism. This turns out to be necessary in order for PLACEHOLDER
        substitution to work properly when the latter type is unconstrained.
 
        * gigi.h (build_unc_object_type_from_ptr): New subprogram, factoring a
        common pattern.
        (maybe_stabilize_reference): New function, like gnat_stabilize_reference
        with extra arguments to control whether to recurse through non-values
        and to let the caller know if the stabilization has succeeded.

        static output of record constructor if all the components are constant.
        (gnat_build_constructor): For a record type, sort the list of field
        initializers in increasing bit position order.
        Factor common code to build a storage type for an unconstrained object
        from a fat or thin pointer type and a constrained object type.
        (build_unary_op) : Always recurse down conversions between
        types variants, and process special cases of VIEW_CONVERT expressions
        as their NOP_EXPR counterpart to ensure we get to the
        CORRESPONDING_VARs associated with CONST_DECls.
        (build_binary_op) : Do not strip VIEW_CONVERT_EXPRs
        on the right-hand side.

        a common pattern.
        (convert) : Return the inner operand directly if we
        are converting back to its original type.
        (convert) : Fallthrough regular conversion code instead of
        extracting the object if converting to a type variant.
        (create_var_decl): When a variable has an initializer requiring code
        generation and we are at the top level, check for a potential violation
        of a No_Elaboration_Code restriction.
        (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
        SIZE and SIZE_UNIT which we need for later back-annotations.
        * utils.c: (convert) : Remove obsolete code.
        : Do not lift the conversion if the target type
        is an unchecked union.
        (pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
        (convert) : When the types have the same

        (Make_Disp_Asynchronous_Select_Spec, Make_Disp_Conditional_Select_Spec,
        Make_Disp_Get_Prim_Op_Kind_Spec, Make_Disp_Timed_Select_Spec): Update
        the names of the generated primitive operations used in dispatching
        selects.
        (Init_Predefined_Interface_Primitives): No need to inherit primitives in
        case of abstract interface types. They will be inherit by the objects
        implementing the interface.
        (Make_DT): There is no need to inherit the dispatch table of the
        ancestor interface for the elaboration of abstract interface types.
        The dispatch table will be inherited by the object implementing the
        interface.
        (Copy_Secondary_DTs): Add documentation.
        (Validate_Position): Improve this static check in case of
        aliased subprograms because aliased subprograms must have
        the same position.
        (Init_Predefined_Interface_Primitives): New subprogram that initializes
        the entries associated with predefined primitives of all the secondary
        dispatch tables.
        (Build_Anonymous_Access_Type): Removed.
        (Expand_Interface_Actuals): With the previous cleanup there is no need
        to build an anonymous access type. This allows further cleanup in the
        code generated by the expander.
        (Expand_Interface_Conversion): If the actual is an access type then
        build an internal function to handle the displacement. If the actual
        is null this function returns null because no displacement is
        required; otherwise performs a type conversion that will be
        expanded in the code that returns the value of the displaced actual.
        (Expand_Interface_Actuals): Avoid the generation of unnecessary type
        conversions that have no effect in the generated code because no
        displacement is required. Code cleanup; use local variables to
        avoid repeated calls to the subprogram directly_designated_type().
 
        * exp_util.ads, exp_util.adb (Is_Predefined_Dispatching_Operation):
        Classify the primitive operations used in dispatching selects as
        predefined.
        (Implements_Limited_Interface): Determine whether some type either
        directly implements a limited interface or extends a type that
        implements a limited interface.
        (Build_Task_Image_Function): Change Subtype_Mark to Result_Definition.
        (Expand_Subtype_From_Expr): Do not build actual subtype if the
        expression is limited.
        (Find_Interface_Tag): Add code to handle class-wide types and
        entities from the limited-view.
 
        * rtsfind.ads: Add entries in RE_Id and RE_Unit_Table for
        Get_Entry_Index, Get_Prim_Op_Kind, POK_Function, POK_Procedure,
        POK_Protected_Entry, POK_Protected_Function, POK_Protected_Procedure,
        POK_Task_Entry, POK_Task_Procedure, Prim_Op_Kind, Set_Entry_Index,
        Set_Prim_Op_Kind.
 
        * sem_ch9.adb (Analyze_Triggering_Alternative): Check for legal type
        of procedure name or prefix that appears as a trigger in a triggering
        alternative.
 
        * uintp.ads: Introduce constants Uint_11 and Uint_13.

        * s-tasini.ads, s-tasini.adb (Defer_Abortion, Undefer_Abortion): Moved
        these procedures to body, and renamed Abort_Defer, Abort_Undefer.
        (Get_Exc_Stack_Addr, Set_Exc_Stack_Addr): Removed, no
        longer used.
 
2005-09-01  Arnaud Charlet  
            Jose Ruiz  
 
        * s-taprop-vxworks.adb:
        Move with clauses outside Warnings Off now that dependent units are
        Preelaborate.
        (Initialize): Call Interrupt_Managemeent.Initialize to ensure proper
        initialization of this unit.
        (Specific): Add new procedures Initialize and Delete so that this
        package can be used for VxWorks 5.x and 6.x
        (ATCB_Key, ATCB_Key_Address): Moved to Specific package body to hide
        differences between VxWorks 5.x and 6.x
        Minor reformatting.
        (Timed_Delay): Remove calls to Defer/Undefer_Abort, now performed by
        caller.
        Use only Preelaborate-compatible constructs.
 
        * s-tpopsp-vxworks.adb (ATBC_Key, ATCB_Key_Addr): Moved from
        Primitives.Operations.
        (Delete, Initialize): New procedures.
 
        * s-osinte-vxworks.adb: Body used to handle differences between
        VxWorks 5.x and 6.x
        (kill, Set_Time_Slice, VX_FP_TASK): New functions.
 
        * s-osinte-vxworks.ads: Minor reformatting.
        Add VxWworks 6.x specific functions (only called from VxWorks 6 files).
        (VX_FP_TASK): Now a function, to handle differences between VxWorks 5
        and 6.
        (Set_Time_Slice): New function, replacing kerneltimeSlice to share code
        between Vxworks 5 and 6.
        (taskLock, taskUnlock): Removeed, no longer used.
 
        * adaint.c: The wait.h header is not located in the sys directory on
        VxWorks when using RTPs.
        (__gnat_set_env_value): Use setenv instead of putenv on VxWorks when
        using RTPs.
        (__gnat_dup): dup is available on Vxworks when using RTPs.
        (__gnat_dup2): dup2 is available on Vxworks when using RTPs.

         SO_RCVTIMEO/SO_SNDTIMEO
         IOV_MAX
 
        * gen-soccon.c:
        Move all target-specific file inclusions and macro definitions to
        gsocket.h, in order to ensure that any C code in socket.c will see a
        set of constants that is consistent with the contents of g-soccon.ads.
 
        * gsocket.h: Code imported from gen-soccon.c:
        Move all target-specific file inclusions and macro definitions to
        gsocket.h, in order to ensure that any C code in socket.c will see a set
        of constants that is consistent with the contents of g-soccon.ads.
        This change also makes gen-soccon self-contained (removing dependencies
        upon GCC internal headers).

            Hristian Kirtchev  
            Javier Miranda  
 
        * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
        from object notation, the original node is unanalyzed and carries no
        semantic information, so that accessiblity checks must be performed on
        the type of the actual itself.
        (Expand_N_Subprogram_Declaration): Change last actual parameter for
        compatibility with Build_Protected_Sub_Specification.
        (Check_Overriding_Inherited_Interfaces): Add suport to handle
        overloaded primitives.
        (Register_Interface_DT_Entry): Use the new name of the formal
        the the calls to Expand_Interface_Thunk

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

2005-09-01  Laurent Pautet  
 
        * 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
        and try again
        Reformating and updated headers.
 
2005-09-01  Javier Miranda  
 
        * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
        that given an entity T creates and returns an Itype that duplicates the
        contents of T. The returned Itype has the null-exclusion

        (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.

        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.

        an access-to-function type with an anonymous access result.

        (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.

        * sem_ch4.adb (Transform_Object_Operation): In a context off the form

        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.

        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

        (Build_Body_To_Inline): Change Set_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

        (Override_Dispatching_Operation): If the previous operation is inherited
        from an interface, it becomes hidden  and does not participate in later
        name resolution.

        * 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.

        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).

        of an entry.
        (Safe_To_Capture_Value): A value (such as non_null) is not safe to

        operation.
        Do not capture values for variables with address clauses.

        * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
        longer needed.
        (InitializeCriticalSection, EnterCriticalSection,

        (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

        (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

        reference the interface tag of the actual object.
        (Expand_Interface_Conversion): New subprogram. Reference the base of
        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.

        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.

        in-out parameter that is a component in an initialization procedure,
        whose constraint might depend on discriminants, and that may be
        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

        previous ones that return the corresponding tag and access_disp_table
        entities.
        (Is_Predefined_Dispatching_Operation): Determines if a subprogram
        is a predefined primitive operation.
        (Expand_Subtype_From_Expr): If the expression is a selected component

        (P_Type_Declaration): Mark as "abstract" the type declarations
        corresponding with protected, synchronized and task interfaces
        (P_Declarative_Items): "not" and "overriding" are overriding indicators
        for a subprogram or instance declaration.
 
        * sem_ch12.adb (Analyze_Subprogram_Instantiation): Verify that an
        instantiation that is a dispatching operation has controlling access

        the generic that is created to represent the formal package.
        (Analyze_Package_Instantiation): Instantiate body immediately if the
        package is a predefined unit that contains inlined subprograms, and
        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.

        error message condition, null procedures are correctly detected now.
        (New_Overloaded_Entity): Bypass trivial overriding indicator check
        for subprograms in the context of protected types. Instead, the
        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

        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

        name in a discriminant constraint of a record component.
        (Resolve_Explicit_Dereference): Do not check whether the type is

        types.
        (Valid_Tagged_Conversion): The conversion of a tagged type to an
        abstract interface type is always valid.
        (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
        pragma Restrictions (No_Obsolescent_Features).
        (Check_Direct_Boolean_Operator): If the boolean operation has been
        constant-folded, there is nothing to check.
        (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
        check on possible violation of restriction No_Direct_Boolean_Operators
        until after expansion of operands, to prevent spurious errors when
        operation is constant-folded.

        2005 users.
        (Analyze_Allocator): For an allocator without an initial value, where
        the designated type has a constrained partial view, a discriminant
        constraint is illegal.

        * a-textio.adb (Set_Col): Fix two errors noticed recently, having to
        do with treatment of Set_Col when positioned at end of line character.

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

        may be deallocated by Normalize_Arguments.
        (Collect_Arguments): Eliminate empty arguments
 
        * gnatcmd.adb (All_Projects): New Boolean flag, initialized to False,
        and set to True when -U is used for GNAT PRETTY or GNAT METRIC.
        (Check_Project): Return False when Project is No_Project. Return True
        when All_Projects is True.
        (GNATCmd): Recognize switch -U for GNAT PRETTY and GNAT METRIC and set

        Has_Specified_Stream_Write (Flag193)
        Present in all type and subtype entities. Set for a given view if the
        corresponding stream-oriented attribute has been defined by an
        attribute definition clause. When such a clause occurs, a TSS is set

        * exp_strm.adb (Build_Mutable_Record_Read_Procedure): Reorganize to
        first read discriminants into temporary objects, performing checks on
        the read values, then possibly performing discriminant checks on the
        actual (if it is constrained), and only finally reading the components
        into a constrained temporary object.
        (Build_Elementary_Input_Call): Adjust the specific circuitry for the

        treated as available for a limited private type if there is an
        attribute_definition_clause that applies to its full view, but not in
        other cases where the attribute is available for the full view

        (Stream_Attribute_Available): New function to determine whether a stream
        attribute is available at a place.

        operation verify that controlling formals of the renamed entity that
        are access parameters are explicitly non-null.

        * exp_aggr.adb (Aggr_Size_OK): An array with no components can always
        be expanded in place. The size computation does not require a
        subtraction, which would raise an exception on a compiler built with
        assertions when the upper bound is Integer'first.
        (Flatten): For an array of composite components, take into account the
        size of the components to determine whether it is safe to expand the

        the "simple_choice" member in a variant record, in accordance with the
        description in the package spec: the information output for a constant
        should be "S number", not "SS number".

        not statically match.

        * 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.

        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,

        abstract types. Set scope of new designator for
        a parameterless subprogram, so that it is available when checking the
        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
        renamings of those.  Clean up spec comments.
        (Check_Dispatching_Context): Add error message to indicate "abstract
        procedure", covering the case of a call to a formal abstract procedure
        that has statically tagged operands.
        (Check_Dispatching_Call): Check for the case of an actual given by
        a tag-indeterminate function call whose type is an ancestor of the
        containing call's associated tagged type. This situation can occur
        for inherited primitives with function defaults. In this case we
        use the tagged type's tag directly as the controlling argument for
        the calls.
        (Expand_Call): Name change on call to Expand_Dispatch_Call.
 
        * sprint.adb (Sprint_Node_Actual): Split
        N_Formal_Subprogram_Declaration into two alternatives for the new
