@topperc i guess if this pass is early enough we'd have an insert_subreg. You're right that the check you pointed out is the one that I wondered if it needed generalising to some kind of "do these two alias". My main thought is that if this was a problem, we'd have already seen it with rv32Zdinx loads and stores, which i think are already supported.
