+	(Record_Type_Declaration): Minor reordering of calls to decorate the

+
+	* g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
+	Command_Line): New types
+	(Define_Alias, Define_Prefix, Free): New subprograms. These provide

+	 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.

+	(Expand_N_Object_Declaration): For the case of a shared passive

+
+	* exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an

+
+	* exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of

+	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

+	(Side_Effect_Free): A selected component of an access type that

+	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

+
+	* sem_ch12.ads, sem_ch12.adb (Instantiate_Type): If the formal is a

+	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.

+	(Resolve_Actuals): When verifying that an access to class-wide object
+	is an actual  for a controlling formal, ignore anonymous access to
+	subprograms whose return type is an access to class_wide type.
+	(Resolve_Slice): If the prefix of the slice is a selected component

+
+	* einfo.ads, einfo.adb (Available_View): New synthesized attribute
+	applicable to types that have the With_Type flag set. Returns the

+	For class-wide types, there is no direct link in the tree, so we have

+	(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.

+	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.

+	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

+	(Expand_Allocator_Expression): Call Adjust for initialized allocators of

+	(Is_In_Place_Function):  If the return type is a limited interface,

+	(Build_Subprogram_Receiving_Stubs, PolyORB):
+	 * Retrieve the extra formals parameters at the

+	(TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,

+	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.

+	(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

+	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
