Subject: [Qemu-devel] [PATCH 1/3] target-tricore: fix OPC2_32_RR_DVINIT_HU having write before use on the result
Date: Fri, 22 May 2015 12:15:56 +0200 [thread overview]
Message-ID: <1432289758-6250-2-git-send-email-kbastian@mail.uni-paderborn.de> (raw)
In-Reply-To: <1432289758-6250-1-git-send-email-kbastian@mail.uni-paderborn.de>
If the argument r1 was the same as the extended result register r3+1, we would
overwrite r1 and then use it.
