Subject: [Qemu-devel] [PATCH 3/5] target-tricore: fix BO_OFF10_SEXT calculating the wrong offset
Date: Tue, 5 May 2015 19:47:01 +0200 [thread overview]
Message-ID: <1430848023-21048-4-git-send-email-kbastian@mail.uni-paderborn.de> (raw)
In-Reply-To: <1430848023-21048-1-git-send-email-kbastian@mail.uni-paderborn.de>
The lower part of the combined offset was sign extended and could lead to
wrong results.
