Subject: [Qemu-devel] [PATCH 19/20] target-sparc: Make cpu_dst local to OP=2 insns
Date: Tue, 16 Oct 2012 19:32:30 +1000 [thread overview]
Message-ID: <1350379951-17615-20-git-send-email-rth@twiddle.net> (raw)
In-Reply-To: <1350379951-17615-1-git-send-email-rth@twiddle.net>
And initialize it such that it (may) write directly to rd.
