--- Comment #24 from Jacob Lifshay <programmerjake at gmail.com> ---
I wrote out the full algorithm, but was stymied trying to get `sv.andi.` to
assemble:

    lst = list(isa)

    yield from self.translate_one(insn)

line 667, in translate_one
    raise Exception("opcode %s of '%s' not supported" %
Exception: opcode andi of 'sv.andi. *80, *47, 15' not supported

I'll debug that more later.
