[regress at apple dot com (regress)]

With your recent patch, GCC HEAD revision 158139 had problems on:

Attached is build output for those targets.
The previous build was of revision 158138.

	* tree.h (TREE_ADDRESSABLE): Document its effect for function types.
	* calls.c (expand_call): Pass the function type to aggregate_value_p.
	* function.c (aggregate_value_p): Do not honor DECL_BY_REFERENCE on
	the target function of a CALL_EXPR.  Honor TREE_ADDRESSABLE on the
	function type instead.  Reorder and simplify checks.

	* gimplify.c (gimplify_modify_expr_rhs) <WITH_SIZE_EXPR>: New case.
ada/
	* gcc-interface/ada-tree.h (TYPE_RETURNS_UNCONSTRAINED_P): Rename into.
	(TYPE_RETURN_UNCONSTRAINED_P): ...this.
	(TYPE_RETURNS_BY_REF_P): Rename into.
	(TYPE_RETURN_BY_DIRECT_REF_P): ...this.
	(TYPE_RETURNS_BY_TARGET_PTR_P): Delete.
	* gcc-interface/gigi.h (create_subprog_type): Adjust parameter names.
	(build_return_expr): Likewise.
	* gcc-interface/decl.c (gnat_to_gnu_entity) <E_Subprogram_Type>:
	Rename local variables.  If the return Mechanism is By_Reference, pass
	return_by_invisible_ref_p to create_subprog_type instead of toggling
	TREE_ADDRESSABLE.  Test return_by_invisible_ref_p in order to annotate
	the mechanism.  Use regular return for contrained types with non-static
	size and return by invisible reference for unconstrained return types
	with default discriminants.  Update comment.
	* gcc-interface/trans.c (Subprogram_Body_to_gnu): If the function
	returns by invisible reference, turn the RESULT_DECL into a pointer.
	Do not handle DECL_BY_REF_P in the CICO case here.
	(call_to_gnu): Remove code handling return by target pointer.  For a
	function call, if the return type has non-constant size, generate the
	assignment with an INIT_EXPR.
	(gnat_to_gnu) <N_Return_Statement>: Remove dead code in the CICO case.
	If the function returns by invisible reference, build the copy return
	operation manually.
	(add_decl_expr): Initialize the variable with an INIT_EXPR.
	* gcc-interface/utils.c (create_subprog_type): Adjust parameter names.
	Adjust for renaming of macros.  Copy the node only when necessary.
	(create_subprog_decl): Do not toggle TREE_ADDRESSABLE on the return
	type, only change DECL_BY_REFERENCE on the RETURN_DECL.
	(convert_from_reference): Delete.
	(is_byref_result): Likewise.
	(gnat_genericize_r): Likewise.
	(gnat_genericize): Likewise.
	(end_subprog_body): Do not call gnat_genericize.
	* gcc-interface/utils2.c (build_binary_op) <INIT_EXPR>: New case.
	(build_return_expr): Adjust parameter names, logic and comment.
