- Subject: [applied mips sim patch] trace "d" shift instructions.
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.)
