Subject: [applied mips sim patch] trace "d" shift instructions.
Date: Fri, 01 Mar 2002 15:26:00 -0000 [thread overview]
Message-ID: <yov5u1rzrht2.fsf@broadcom.com> (raw)
When looking through my list of old patches, I noticed that in the
last few days i'd gotten around to putting in some changes which i'd
submitted back in 12/2002... (I'd forgotten about my old patches.)
That led me to wondering what else of those i was missing. This is
one chunk.
(verified that various sims still build w/ it.)
