Hello Jakub, I must confess that in the last months I've not been able to find much time (I do this in my spare time) to work on this. Part of the problem is also that my new employer hasn't yet provided a written copyright waiver for the FSF, though they have agreed and my contract already w

I think you can use pdp11 as an example, it does two things that are similar to what you're describing. One is that it requires SImode to go into an even regno, and indicates that it uses two registers. See TARGET_HARD_REGNO_MODE_OK and TARGET_HARD_REGNO_NREGS. The other is that it has one
