[PATCH 12/13] gdbarch software_single_step frame_info to regcache: spu

[Yao Qi <qiyaoltc@gmail.com>]

gdb:

2016-11-10  Yao Qi  <yao.qi@linaro.org>

	* spu-tdep.c (spu_software_single_step): Call get_regcache_arch
	instead of get_frame_arch.  Call regcache_read_pc instead of
	get_frame_pc.  Call regcache_raw_get_unsigned instead of
	get_frame_register_unsigned.
