Subject: [Qemu-devel] [PATCH 10/20] target-sparc: Tidy gen_branch_a interface
Date: Tue,  1 Sep 2015 22:51:53 -0700	[thread overview]
Message-ID: <1441173123-25540-11-git-send-email-rth@twiddle.net> (raw)
In-Reply-To: <1441173123-25540-1-git-send-email-rth@twiddle.net>

We always pass pc2 == dc->npc and r_cond == cpu_cond,
and always set is_br afterward.  Infer all of that.
