Subject[PATCH 14/41] m68k: broken constraints on mulu.l
From
Date
From: Al Viro <viro@zeniv.linux.org.uk>
Date: 1133436151 -0500

too permissive constraint on mulu.l - the first argument should not be
an a-register. Fixed by replacing "g" with "dm"; with older gcc we got
lucky and it had never attempted mulu.l %a0, %d1:%d0. These days it
does, with predictable objections from as(1).

Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
