Subject: xstormy16: more misalignment fixes.
X-SW-Source: 2003-q2/txt/msg00014.txt.bz2


Yet more fixes for the xstormy16 word-alignment rules.

[cgen]
2003-05-01  DJ Delorie  <dj@redhat.com>

	* cpu/xstormy16.cpu (alignfix-mem): Correct logic for unaligned
	word accesses.
	(set-alignfix-mem): Likewise.

[sid/component/cgen-cpu/xstormy16]
