Subject: [Qemu-devel] [PATCH 08/14] tcg-sparc: Change AREG0 in generated code to %i0.
Date: Fri, 21 Sep 2012 19:05:01 -0700 [thread overview]
Message-ID: <1348279507-3617-9-git-send-email-rth@twiddle.net> (raw)
In-Reply-To: <1348279507-3617-1-git-send-email-rth@twiddle.net>
We can now move the TCG variable from %g[56] to a call-preserved
windowed register.
