[Qemu-devel] [PATCH 10/20] target-sparc: Tidy gen_branch_a interface


From: Richard Henderson
Subject: [Qemu-devel] [PATCH 10/20] target-sparc: Tidy gen_branch_a interface
Date: Tue, 1 Sep 2015 22:51:53 -0700

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