From 7f2633388d64c0489516af04e0d4cd9f01397a94 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Thu, 12 Jan 2006 01:06:19 -0800 Subject: [PATCH] [PATCH] m68k: broken constraints on mulu.l 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).
