	    Gary Dismukes  <dismukes@adacore.com>

	* gigi.h: (tree_code_for_record_type): Declare.
	(add_global_renaming_pointer): Rename to record_global_renaming_pointer.

	(get_global_renaming_pointers): Declare.
	(add_global_renaming_pointer): Likewise.

	* ada-tree.h (DECL_READONLY_ONCE_ELAB): New macro.

	imported_p.
	<E_Access_Type>: Use the Non_Limited_View as the full view of the

	incomplete designated type if it is in the main unit and has a freeze
	node.
	<E_Incomplete_Type>: Rework to treat Non_Limited_View, Full_View, and
	Underlying_Full_View similarly.  Return earlier if the full view already
	has an associated tree.

	TREE_READONLY set.
	(gnat_to_gnu_entity, case E_Enumeration_Type): Set TYPE_NAME
	for Character and Wide_Character types. This info is read by the
	dwarf-2 writer, and is needed to be able to use the command "ptype
	character" in the debugger.
	(gnat_to_gnu_entity): When generating a type representing
	a Character or Wide_Character type, set the flag TYPE_STRING_FLAG,
	so that debug writers can distinguish it from ordinary integers.
	(elaborate_expression_1): Test the DECL_READONLY_ONCE_ELAB flag in
	addition to TREE_READONLY to assert the constantness of variables for
	elaboration purposes.
	(gnat_to_gnu_entity, subprogram cases): Change loops on formal
	parameters to call new Einfo function First_Formal_With_Extras.
	(gnat_to_gnu_entity): In type_annotate mode, replace a discriminant of a

	for a multiple elaboration of the "equivalent" type.
	(gnat_to_gnu_entity): Adjust for renaming of add_global_renaming_pointer

	(gnat_to_gnu_entity) <E_Incomplete_Subtype>: Add support for regular
	incomplete subtypes and incomplete subtypes of incomplete types visible
	through a limited with clause.

	the base index type for the maximum size of the array only if they are
	constant.

	expression into a SAVE_EXPR if stabilization failed.

	* utils.c (create_subprog_decl): Turn TREE_ADDRESSABLE on the type of
	a result decl into DECL_BY_REFERENCE on this decl, now what is expected
	by lower level compilation passes.
	(gnat_genericize): New function, lowering a function body to GENERIC.
	Turn the type of RESULT_DECL into a real reference type if the decl
	has been marked DECL_BY_REFERENCE, and adjust references to the latter
	accordingly.
	(gnat_genericize_r): New function. Tree walking callback for
	gnat_genericize.
	(convert_from_reference, is_byref_result): New functions. Helpers for
	gnat_genericize_r.
	(create_type_decl): Call gnat_pushdecl before calling
	rest_of_decl_compilation, to make sure that field TYPE_NAME of
	type_decl is properly set before calling the debug information writers.
	(write_record_type_debug_info): The heuristics which compute the
	alignment of a field in a variant record might not be accurate. Add a
	safety test to make sure no alignment is set to a smaller value than
	the alignment of the field type.
	(make_dummy_type): Use the Non_Limited_View as the underlying type if
	the type comes from a limited_with clause. Do not loop on the full view.
	(GET_GNU_TREE, SET_GNU_TREE, PRESENT_GNU_TREE): New macros.
	(dummy_node_table): New global variable, moved from decl.c.
	(GET_DUMMY_NODE, SET_DUMMY_NODE, PRESENT_DUMMY_NODE): New macros.
	(save_gnu_tree): Use above macros.

	create_var_decl_1 allowing CONST_DECL creation.
	(create_true_var_decl): New function, similar to create_var_decl but
	forcing the creation of a VAR_DECL node (CONST_DECL not allowed).
	(create_field_decl): Do not always mark the field as addressable
	if its type is an aggregate.
	(global_renaming_pointers): New static variable.
	(add_global_renaming_pointer): New function.
	(get_global_renaming_pointers): Likewise.

	(LANG_HOOKS_WRITE_GLOBALS): Define to gnat_write_global_declarations.

	exception handler volatile if it is of variable size.

	actual, convert the corresponding gnu_actual to the real destination
	type when necessary.
	(add_decl_expr): Set the DECL_READONLY_ONCE_ELAB flag on variables
	originally TREE_READONLY but whose elaboration cannot be performed
	statically.
	Part of fix for F504-021.
	(tree_transform, subprogram cases): Change loops on formal parameters to
	call new Einfo function First_Formal_With_Extras.
	(gnat_to_gnu) <N_Op_Shift_Right_Arithmetic>: Ignore constant overflow
	stemming from type conversion for the lhs.

	compilation unit.
	(elaborate_all_entities): Do not retest type_annotate_only.
	(tree_transform) <N_Abstract_Subprogram_Declaration>: Process the
	result type of an abstract subprogram, which may be an itype associated

	indexed component; the former is legal in Ada 2005; the latter is not.
	(Analyze_Allocator): Correct code for AI-287 -- extension aggregates
	were missing. We also didn't handle qualified expressions. Now also
	allow function calls. Use new common routine OK_For_Limited_Init.
	(Analyze_Type_Conversion): Do not perform some legality checks in an
	instance, because the error message will be redundant or spurious.
	(Analyze_Overloaded_Selected_Component): Do not do style check when
	setting an entity, since we do not know it is the right entity yet.
	(Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
	(Analyze_Overloaded_Selected_Component): Same change
	(Analyze_Selected_Component): Remove unnecessary prefix type retrieval
	since regular incomplete subtypes are transformed into corresponding
	subtypes of their full views.
	(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
	with base type of object to determine whether it is a primitive
	operation.
	(Operator_Check): If no interpretation of the operator matches, check
	whether a use clause on any candidate might make the operation legal.
	(Try_Class_Wide_Operation): Check whether the first parameter is an
	access type whose designated type is class-wide.

        * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
	that has been constant-folded, preserve information of original tree,
	for ASIS uses.
	(Analyze_Formal_Derived_Type): Set the limited present flag of the newly
	generated private extension declaration if the formal derived type is
	synchronized. Carry synchronized present over to the generated private
	extension.
	(Validate_Derived_Type_Instance): Ensure that the actual of a
	synchronized formal derived type is a synchronized tagged type.
	(Instantiate_Formal_Package): When creating the instantiation used to
	validate the actual package of a formal declared without a box, check
	whether the formal itself depends on a prior actual.
	(Instantiate_Formal_Subprogram): Create new entities for the defining
	identifiers of the formals in the renaming declaration, for ASIS use.
	(Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
	a renaming declaration or a subtype declaration for an actual in an
	instance, capture location information of declaration in generic, for
	ASIS use.
	(Instantiate_Formal_Package): Add comments on needed additional tests.
	AI-317 (partial parametrization) is fully implemented.
	(Validate_Private_Type_Instance): Add check for actual which
	must have preelaborable initialization
	Use new // insertion for some continuation messages
	(Analyze_Formal_Object_Declaration): Change usage of Expression to
	Default_Expression. Add type retrieval when the declaration has an
	access definition. Update premature usage of incomplete type check.
	(Check_Access_Definition): New subsidiary routine. Check whether the
	current compilation version is Ada 05 and the supplied node has an
	access definition.
	(Instantiate object): Alphabetize local variables. Handle the creation
	of new renaming declarations with respect to the kind of definition
	used - either an access definition or a subtype mark. Guard against
	unnecessary error message in the context of anonymous access types after
	they have been resolved. Add check for required null exclusion in a
	formal object declaration.
	(Switch_View): A private subtype of a non-private type needs to be
	switched (the base type can have been switched without its private
	dependents because of the last branch of Check_Private_View.
	(Check_Private_View): Do not recompute Base_Type (T), instead use cached
	value from BT.
	(Instantiate_Type): Emit an error message whenever a class-wide type of
	a tagged incomplete type is used as a generic actual.
	(Find_Actual_Type): Extend routine to handle a component type in a child
	unit that is imported from a formal package in a parent.
	(Validate_Derived_Type_Instance): Check that analyzed formal and actual
	agree on constrainedness, rather than checking against ultimate ancestor
	(Instantiate_Subprogram_Body): Create a cross-reference link to the
	generic body, for navigation purposes.

	attribute whose prefix is the type of an enclosing aggregate.
	Generalizes previous mechanism to handle attribute references nested
	arbitrarily deep within the aggregate.
	(Analyze_Access_Attribute): An access attribute whose prefix is a type
	can appear in an aggregate if this is a default-initialized aggregate
	for a self-referential type.

	Has_Specified_Stream_Attribute flag.
	Disallow Storage_Size and Storage_Pool for access to subprogram
	(Resolve_Attribute, case 'Access et al): Take into account anonymous
	access types of return subtypes in extended return statements. Remove
	accessibility checks on anonymous access types when Unchecked_Access is
	used.
	(Analyze_Attribute): Add support for the use of 'Class to convert
	a class-wide interface to a tagged type.
	Add support for the attribute Priority.
	(Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
	whether the designated type is discriminated with a constrained partial
	view and require static matching in that case.
	Add local variable Des_Btyp. The Designated_Type
	of an access to incomplete subtype is either its non-limited view if
