	* frame.c (get_frame_memory_signed): New function.
	(get_frame_memory, get_frame_memory_unsigned): New function.
	(get_frame_arch): New function.
	* frame.h (get_frame_signed_memory, get_frame_arch): Declare.
	(get_frame_memory, get_frame_unsigned_memory): Declare.
	* d10v-tdep.c (d10v_frame_unwind_cache): Use
	get_frame_memory_unsigned and get_frame_arch.
	(d10v_frame_unwind_cache, saved_regs_unwinder): Ditto.
