+ E_Constant, depending upon Variable formal.
+ (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
+ PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
+ 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

+ When expanding a package spec, this list correspond to the

+ (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.

+ (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.

+ (Analyze_Formal_Object_Declaration): Add check for illegal default

+ (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-

+ the stack as well.
+ (Analyze_Call): Remove restriction on calls to limited functions for the

+
+ * g-awk.adb (Default_Session, Current_Session): Compile this file in

+
+ * g-awk.ads: Use overloaded subprograms in every case where we used to

+ 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

+ Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.

+
+ * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from

+ 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

+ (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

+ 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

+ (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

+ (Layout_Variant_Record): Retrieve the discriminants from the entity

+ (Layout_Component_List): When applying the Max operator to variants with

+ (Layout_Type): In VMS, if a C-convention access type has no explicit

+ * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we

+ (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

+ (Analyze_Call): Add additional warnings for function call contexts not

+ (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.

+ were missing. We also didn't handle qualified expressions. Now also

+ (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res

+ (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

+ (Operator_Check): If no interpretation of the operator matches, check
