New Revision: 225925

URL: https://gcc.gnu.org/viewcvs?rev=225925&root=gcc&view=rev
Log:
	* expmed.c (flip_storage_order): Deal with complex modes specially.
	Use the precision of the mode instead of its size to find an integral
	counterpart.
	(extract_bit_field_1): Deal with complex modes specially.
	* expr.c (read_complex_part): Make public.
	(get_inner_reference): Call reverse_storage_order_for_component_p.
	(expand_expr_real_1): Allow early exit for CONCATs as well.
	* expr.h (read_complex_part): Declare.
	* tree-dfa.c (get_ref_base_and_extent): Call
	reverse_storage_order_for_component_p.
	* tree.h (reverse_storage_order_for_component_p): New inline predicate.
ada/
	* freeze.adb (Check_Component_Storage_Order): Skip a record component
	if it has Complex_Representation.
	(Freeze_Record_Type): If the type has Complex_Representation, skip
	the regular treatment of Scalar_Storage_Order attribute and instead
	issue a warning if it is present.
testsuite/
	* c-c++-common/sso/init13.h: New helper.
	* c-c++-common/sso/p13.c: New test.
	* c-c++-common/sso/q13.c: Likewise.
	* c-c++-common/sso/t13.c: Likewise.
	* gnat.dg/sso/init13.ads: New helper.
	* gnat.dg/sso/p13.adb: New test.
	* gnat.dg/sso/q13.adb: Likewise.
	* gnat.dg/sso/t13.adb: Likewise.
