Upstream-Status: Inappropriate [Backport]
From 14fb9260e8c94249305dba567e7e242ac3d30fa7 Mon Sep 17 00:00:00 2001
From: uros <uros@138bc75d-0d04-0410-961f-82ee72b054a4>

Subject: [PATCH 037/200] * config/alpha/alpha.c (alpha_sr_alias_set): Don't define.
(alpha_option_override): Don't set alpha_sr_alias_set.
(emit_frame_store_1): Use gen_frame_mem rather than calling
set_mem_alias_set.
(alpha_expand_epilogue): Ditto.
(unicosmk_gen_dsib): Ditto.
