        * misc.c (internal_error_function): Don't use vsprintf to format
        the error message text, instead use pp_format_text and the new
        pretty printer APIs.  This allows handling of %qs, %w, etc.

        it did not matter because we always rewrote a/=b to not(a=b).

        <E_Record_Type>: Likewise.
        (gnat_to_gnu_entity) <object, renaming>: 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.

        type imported through a limited_with clause, use its non-limited view.

        (gnat_to_gnu_entity) <E_Variable>: Decrement force_global if necessary
        before early-returning for certain types when code generation is
        disabled.
        (gnat_to_gnu_entity) <object>: 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) <object>: When turning a non-definition of an
        object with an address clause into an indirect reference, drop the

        related): For a prefix that is a dereference of a fat or thin pointer,
        if there is an actual subtype provided by the front-end, use that
        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.
        (gnat_to_gnu): When adding a statement into an elaboration procedure,
        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.

        * utils2.c (gnat_build_constructor): Only sort the fields for possible
        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) <ADDR_EXPR>: 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) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
        on the right-hand side.

        * utils.c (build_unc_object_type_from_ptr): New subprogram, factoring
        a common pattern.
        (convert) <VIEW_CONVERT_EXPR>: Return the inner operand directly if we
        are converting back to its original type.
        (convert) <JM input>: 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) <STRING_CST>: Remove obsolete code.
        <VIEW_CONVERT_EXPR>: Do not lift the conversion if the target type
        is an unchecked union.
        (pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
        (convert) <VIEW_CONVERT_EXPR>: When the types have the same
        main variant, just replace the VIEW_CONVERT_EXPR.
        <UNION_TYPE>: Revert 2005-03-02 change.

        * repinfo.h, repinfo.ads: Add tcode for BIT_AND_EXPR.

        * repinfo.adb (Print_Expr, Rep_Value): Handle Bit_And_Expressions.

        'Unrestricted_Access, if the designated type is an interface we

        suppressed.

        (Expand_N_Return_Statement): When returning a mutable record, convert
        the return value into its actual subtype in order to help the backend

        parent unit associated with a generic child unit instance (associated
        with the existing Parent_Unit_Visible flag).

        parents recorded in the global Instance_Parent_Unit.
        (Init_Env): Save value of Instance_Parent_Unit in the Instance_Env
        stack.
        (Install_Spec): Save the parent unit entity in Instance_Parent_Unit when
        it's not a top-level unit, and only do this if Instance_Parent_Unit is
        not already set. Replace test of Is_Child_Unit with test of parent's
        scope against package Standard. Add comments and a ??? comment.
        (Remove_Parent): Revise condition for resetting Is_Immediately_Visible
        on a child instance parent to test that the parent equals
        Instance_Parent rather than simply checking that the unit is not a
        child unit.
        (Restore_Env): Restore value of Instance_Parent_Unit from Instance_Env.
        (Validate_Derived_Interface_Type_Instance): Verify that all ancestors of
        a formal interface are ancestors of the corresponding actual.
        (Validate_Formal_Interface_Type): Additional legality checks.
        (Analyze_Formal_Derived_Interface_Type): New procedure to handle formal
        interface types with ancestors.

        * sem_ch3.ads, sem_ch3.adb (Build_Discriminal): Add link to original
        discriminant.
        (Build_Private_Derived_Type): The entity of the created full view of the
        derived type does not come from source. If after installing the private
        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.
        (Derive_Interface_Subprograms): No need to derive subprograms
        of ancestors that are interfaces.
        (Derive_Subprograms): Remove formal No_Predefined_Prims and the

        (Complete_Subprograms_Derivation): Handle the case in which the full
        view is a transitive derivation of the ancestor of the partial view.
        (Process_Full_View): Rename local subprogram Find_Interface_In_
        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
        partial view, inherit properly its primitive operations.
        (Collect_Interfaces): Make public, for analysis of formal
        interfaces.
        (Analyze_Interface_Declaration): New procedure for use for regular and
        formal interface declarations.
        (Build_Derived_Record_Type): Add support for private types to the code
        that checks if a tagged type implements abstract interfaces.
        (Check_Aliased_Component_Type): The test applies in the spec of an
        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.
        (Collect_Interfaces): For private extensions and for derived task types
        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.

        appear immediately after a subprogram body, when there is no previous
        subprogram declaration.
        Change name Is_Package to Is_Package_Or_Generic_Package
        (Process_Formals): A non null qualifier on a non null named access
        type is not an error, and is a warning only if Redundant_Constructs
        are flagged.

        nested within Analyze_Package_Specification to install the private
        declarations and use clauses within each of the parent units of a
        package instance of a generic child package.
        (Analyze_Package_Specification): When entering a private part of a
        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).
        Change name Is_Package to Is_Package_Or_Generic_Package
        (Preserve_Full_Attributes): For a synchronized type, the corresponding
        record is absent in a generic context, which does not indicate a
        compiler error.

        * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
        not try to rewrite a renamed stream attribute, because the operations
        on the type may not have been generated.
        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.
        (Note_Redundant_Use): Emit a warning when a redundant use clause is
        detected.
        (Analyze_Object_Renaming): An attribute reference is not a legal object
        if it is not a function call.

        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

        (Expand_Subtype_From_Expr): Do not build actual subtype if the
        expression is limited.

        * 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.

2005-09-01  Laurent Pautet  <pautet@adacore.com>

        * 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.

        the error location.
        (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
        a function renaming thereof, is a valid prefix for 'Size (where it is
        intepreted as a function call).
        (Statically_Denotes_Entity): New predicate to determine whether the

        * 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.

        rather than copying the entity of the spec, to prevent accidental
        sharing of the entity list.
        (Check_Private_View): When exchanging views of private types, build the
        list of exchanged views as a stack, to ensure that on exit the exchanges
        are undone in the proper order.
        (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):

        * 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.

        * 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

        (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies

        (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

        * 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.

        * 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.

            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-posix.ads, s-taspri-vxworks.ads, s-taspri-mingw.ads,

        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.

        * s-intman.ads, s-intman-irix.adb, s-intman-irix-athread.adb,
        s-intman-dummy.adb, s-intman-solaris.adb, s-intman-vms.adb,

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

        * s-interr.adb: Add explicit call to Setup_Interrupt_Mask now that

        (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

        (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

        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.

        that they cannot contain interrupt handlers if not declared at library
        level.

        we are in the case of an abstact-interface derivation
        (Find_Type_Of_Subtype_Indic): Moved from the body of the package

        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

        (Is_Predefined_Dispatching_Operation): Determines if a 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
