Subject: [Qemu-devel] [PATCH 06/13] tcg: improve tcg_reg_alloc_movi()
Date: Thu, 27 Sep 2012 19:15:06 +0200 [thread overview]
Message-ID: <1348766113-18373-7-git-send-email-aurelien@aurel32.net> (raw)
In-Reply-To: <1348766113-18373-1-git-send-email-aurelien@aurel32.net>
Now that the liveness analysis might mark some output temps as dead, call
temp_dead() if needed.
