Yes, but none of those are of great importance, and can be worked
around. Apart from the FF1 opcode ("Find First One", an opcode to find
the first 1-bit in an operator), they all belong to things such as the
MAC/EMAC ((Enhanced) Multiply ACcumulator, for hardware-accelerated
vector math) or the crypto accelerator units.

Obviously it'd be nice to get liboil and friends to use those opcodes,
but regular programs that don't need vector math can live perfectly fine
without them.

I didn't :)

I don't think that's the case. Could be wrong, though.

Sounds like a better solution indeed.
