* d10v-tdep.c (d10v_unwind_dummy_id): New function.
(d10v_gdbarch_init): Set unwind_dummy_id and save_dummy_frame_tos.
* frame.c (get_prev_frame): Restructure the frame ID unwind code
to use unwind_dummy_id when a dummy frame.
* gdbarch.sh (unwind_dummy_id): New multi-arch method with
predicate.
* gdbarch.h, gdbarch.c: Regneerate.
