That's patch 7/17. ;-)
Woops , I just realized ;-)
R0 is not an *architectural* zero. It's a software convention. The
spec is fairly clear on this point.
I agree that there ought to be some special-casing of the software
convention, but that should require a TB flag to verify the convention
is followed. But even then I would not bother retaining the special
case here in multiply. I would only use it in the "move" and constant
formation types of pseudo instructions (or, ori, etc).
That sounds reasonable and is clearly for another patch, so
