gdbarch software_single_step frame_info to regcache: sparc
gdb:
2016-11-22 Yao Qi <yao.qi@linaro.org>
* sparc-tdep.c (sparc_analyze_control_transfer): Replace parameter
frame with regcache. Call get_current_frame.
(sparc_software_single_step): Call get_regcache_arch instead of
get_frame_arch. Call regcache_raw_get_unsigned instead of
get_frame_register_unsigned.
