[PATCH] Don't handle unavailable/optimized-out in spu_software_single_step
- From: Yao Qi <qiyaoltc at gmail dot com>

- Subject: [PATCH] Don't handle unavailable/optimized-out in spu_software_single_step
- Authentication-results: sourceware.org; auth=none
When we do software single step, frame is always the innermost one,
so it is impossible to get unavailable/optimized-out errors.

* spu-tdep.c (spu_software_single_step): Don't call
get_frame_register_bytes, call get_frame_register_unsigned
instead.
