that is *exactly* my concern (and not how to handle temporaries, that's
a no-brainer).  not sure if i didn't express myself clearly before, but
limiting to only use 16 registers would mean to alter calling
conventions because we cannot use a6 and a7 for argument passing.
one could certainly get it "to work", but leaving the specs does neither
simplify verification nor does it diminish work-load.


do you have links to that minimalistic RISC-V you're talking about?
that might help :)
