Unless I'm misreading ocavr32.pdf, that should be (R12, R10:R11, R9, R8) and

fadvise64_64 does. And something like (s32, s32, s64, s64) would turn into
(R12, R11, R9:R8, stack, stack); AFAICS, we don't have anything that ugly...

Automating *that* is going to be interesting... I've not given up, but it's
not going to be fun ;-/


Feel free to steal machinery from klibc... it has scripts to autogenerate stubs for arbitrary ABIs.
