2016-11-22  Yao Qi  <yao.qi@linaro.org>

	* alpha-tdep.c (alpha_deal_with_atomic_sequence): Call
	get_regcache_arch instead of get_frame_arch.  Call
	regcache_read_pc instead of get_frame_pc.
	(alpha_next_pc): Replace parameter frame with regcache.
	Call regcache_raw_get_unsigned instead of
	get_frame_register_unsigned.
