[Qemu-devel] [PATCH] target-tricore: fix RRPW_DEXTR using wrong reg

From: Bastian Koppelmann
Subject: [Qemu-devel] [PATCH] target-tricore: fix RRPW_DEXTR using wrong reg
Date: Mon, 23 Mar 2015 14:55:56 +0000

RRPW_DEXTR used r1 for the low part and r2 for the high part. It should be the
other way round. This also fixes that the result of the first shift was not
saved in a temp and could overwrite registers that were needed for the second
