Subject: [Qemu-devel] [PATCH v4 11/18] tcg-arm: Use R12 for the tcg temporary
Date: Sat, 30 Mar 2013 13:43:20 -0700 [thread overview]
Message-ID: <1364676207-21516-12-git-send-email-rth@twiddle.net> (raw)
In-Reply-To: <1364676207-21516-1-git-send-email-rth@twiddle.net>
R12 is call clobbered, while R8 is call saved. This change
gives tcg one more call saved register for real data.
