My bad, thanks for clarifying.

That's the only thing that caught my eye.  I think for most v9 chips a
'return' is slightly more expensive than a 'ret/restore'.  'return' is
good for saving an instruction when you can put something in that
delay slot, but if you can't then you might as well do 'ret/restore'.

Series otherwise looks great, nice work!
