* frame.c (frame_unwind_register): New function.
(frame_unwind_unsigned_register): Use.
(frame_unwind_signed_register): Use.
(frame_read_register): New function.
* frame.h (frame_unwind_register): Declare.
(frame_read_register): Declare.
* d10v-tdep.c (d10v_frame_pop): Rewrite. Use regcache_cooked_write
and frame_unwind_register instead of read_memory, write_register and
deprecated_write_register_bytes.
