Not quite the same. tx39 pretends to be MIPS1, and then adds in the
MIPS2 instructions that it does have. Apollo however is missing a few
MIPS1 instructions, div for instance. I can't disable that without
messing up the mips-opc.c file, and I didn't think that was appropriate
for the Apollo port.
Anyways, there seems to be some disagreement about my approach, so I
will take a look at my alternatives. It may be a while before I get
back to this, as I have other work to do.
