From: Alexandre Oliva <aoliva@redhat.com>
Date: Wed, 9 Aug 2000 18:42:04 +0000
Subject: * am33.igen: Warning clean-up. (movm): Initialize PC and mask. (mov,
 movbu, movhu): Set srcreg2 from RI0. (bsch): Initialize c. (sat16_cmp):
 Actually do the comparison. (mov_llt): Do not overwrite dstreg with
 uninitialized variable.
