[Qemu-devel] [PATCH v2 02/60] target-i386: Push DisasContext into load/s


From: Richard Henderson
Subject: [Qemu-devel] [PATCH v2 02/60] target-i386: Push DisasContext into load/store helpers
Date: Fri, 29 Nov 2013 15:59:49 +1300

Rather than add s->mem_index into a combined size+mem_index
argument, pass the context down.  This will allow cleaning
up s->mem_index later.
