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

	clean up, the functionality of this subprogram is now provided
	by Set_All_DT_Position.

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

	(Check_Anonymous_Access_Types): Before full analysis of a record type
	declaration, create anonymous access types for each self-referential
	access component.
	(Analyze_Component_Declaration, Array_Type_Declaration): Indicate that
	an access component in this context is a Local_Anonymous_Access, for
	proper accessibility checks.

	definition.
	(Complete_Subprograms_Derivation): New subprogram used to complete
	type derivation of private tagged types implementing interfaces.
	In this case some interface primitives may have been overriden
	with the partial-view and, instead of re-calculating them, they
	are included in the list of primitive operations of the full-view.
	(Build_Derived_Record_Type): Modified to give support to private
	types implemening interfaces.
	(Access_Definition): Reject ALL on anonymous access types.
	(Build_Derived_Record_Type): In the case of Ada 2005, allow a tagged

	* exp_ch3.adb: Implement config version of persistent_bss pragma
	(Check_Stream_Attributes): Use Stream_Attribute_Available instead of

	a scalar temporary marked as internal.

	* exp_ch6.adb (Add_Simple_Call_By_Copy_Code): Handle properly an
	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
	internal, so that no useless scalar normalization is generated for it.

	null procedure can always be inlined.
	(Expand_N_Subprogram_Declaration): If this is the declaration of a null

	interface.
	(Find_Interface_Tag): New overloaded subprogram. Subsidiary to the
	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
	within an initialization procedure, compute its actual subtype, because
	the component may depend on the discriminants of the enclosing record.

	* 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
	dummy package that uses declarations available at a-tags.ads

	* par-ch3.adb (P_Identifier_Declarations): Give an error for use of
	"constant access" and "aliased [constant] access" when not compiling
	with -gnat05.
	Suppress Ada 2005 keyword warning if -gnatwY used

	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.

	* sem_ch6.adb, sem_ch9.adb (Analyze_Subprograms_Declaration): Update
	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.

	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
	that it is consistent with the overrinding status of the subprogram
	at this point.
	(Analyze_Subprogram_Declaration): Indicate that a null procedure is
	always inlined.
	If the subprogram is a null procedure, indicate that it does not need
	a completion.

	* sem_disp.adb (Check_Controlling_Type): Give support to entities
	available through limited-with clauses.

	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
	allocator's expression or subtype indication is not statically deeper
	than the level of the allocator's access type.
	(Check_Discriminant_Use): Diagnose discriminant given by an expanded
	name in a discriminant constraint of a record component.
	(Resolve_Explicit_Dereference): Do not check whether the type is
	incomplete when the dereference is a use of an access discriminant in
	an initialization procedure.
	(Resolve_Type_Conversion): Handle conversions to abstract interface
	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.

	* sem_type.ads, sem_type.adb (Covers, Intersect_Types, Specific_Type,
	Has_Compatible_Type): Modified to give support to abstract interface
	types.
	(Interface_Present_In_Ancestor): New function to theck if some ancestor
	of a given type implements a given interface

	* sem_ch4.adb (Analyze_Call): Handle properly an indirect call whose
	prefix is a parameterless function that returns an access_to_procedure.
	(Transform_Object_Operation): Handle properly function calls of the
	form Obj.Op (X), which prior to analysis appear as indexed components.
	(Analyze_One_Call): Complete the error notification to help new Ada
	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.

	* tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
	exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
	uses of the Access_Disp_Table attribute to reference the first dispatch
	table associated with a tagged type. As
	part of the implementation of abstract interface types,

	(Component_Equality): When returning an N_Raise_Program_Error statement,
	ensure that its Etype is set to Empty to avoid confusing GIGI (which

	(Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
	determine the amount of data to be copied.

	* par.adb (P_Interface_Type_Definition): New subprogram that parses the

	ARG, and it is easy enough to use a different example.

	* s-wchcon.ads, s-wchcnv.ads, s-wchcnv.adb: Add new subprograms for

	describing the new layout.
	(Dispatch_Table): The expander computes the actual array size, allocates

	(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.

	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

	the calls.

	component definitions.

	components.
	(Array_Type_Declaration): Give support to access components. In addition
	it was also modified to reflect the name of the object in anonymous
	array types. The old code did not take into account that it is possible
	to have an unconstrained anonymous array with an initial value.
	(Check_Or_Process_Discriminants): Allow access discriminant in
	non-limited types.
	(Process_Discriminants): Allow access discriminant in non-limited types
	Initialize the new Access_Definition field in N_Object_Renaming_Decl

2004-02-02  Jose Ruiz  <ruiz@act-europe.fr>

	* restrict.adb: Use the new restriction identifier
	No_Requeue_Statements instead of the old No_Requeue for defining the
	restricted profile.

	* sem_ch9.adb (Analyze_Requeue): Check the new restriction
	No_Requeue_Statements.

	* s-rident.ads: Adding restriction No_Requeue_Statements (AI-00249)
	that supersedes the GNAT specific restriction No_Requeue. The later is
	kept for backward compatibility.

2004-02-02  Ed Schonberg  <schonberg@gnat.com>

	* lib.ads, i-cobol.ads, * s-stoele.ads, s-thread.ads, style.ads,
	5staprop.adb, atree.adb, atree.ads, g-crc32.ads: Remove redundant
	pragma and fix incorrect ones.

	* sem_prag.adb For pragma Inline and pragma Pure_Function, emit a
	warning if the pragma is redundant.

	annotating types.

2004-02-02  Olivier Hainque  <hainque@act-europe.fr>

	* init.c (__gnat_install_handler): Setup an alternate stack for signal
	handlers in the environment thread. This allows proper propagation of
	an exception on stack overflows in this thread even when the builtin
	ABI stack-checking scheme is used without support for a stack reserve
	region.

	* utils.c (create_field_decl): Augment the head comment about bitfield
	creation, and don't account for DECL_BIT_FIELD in DECL_NONADDRESSABLE_P
	here, because the former is not accurate enough at this point.
	Let finish_record_type decide instead.
	Don't make a bitfield if the field is to be addressable.
	Always set a size for the field if the record is packed, to ensure the
	checks for bitfield creation are triggered.
	(finish_record_type): During last pass over the fields, clear
	DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is
	not covered by the calls to layout_decl.  Adjust DECL_NONADDRESSABLE_P
	from DECL_BIT_FIELD.

2003-12-03  Jose Ruiz  <ruiz@act-europe.fr>

2003-12-03  Ed Schonberg  <schonberg@gnat.com>

	* sem_attr.adb:
	(Legal_Formal_Attribute): Attribute is legal in an inlined body, as it
	is legal in an instance, because legality is cheched in the template.

	* sem_prag.adb:
	(Analyze_Pragma, case Warnings): In an inlined body, the pragma may be
	appplied to an unchecked conversion of a formal parameter.

	* sem_warn.adb:
