Re: [9fans] Non-stack-based calling conventions

["Paweł Lasek" <pawel.lasek@gmail.com>]

I don't have latest version of fascicle one (MMIX processor
architecture and MMIXAL assembler language, from new version of The
Art of Computer Programming) at hand, so I can't confirm it, but I
remember that MMIX had a special register which implemented a
"border", shifting register numbers to use them for procedure data
separation.

And as in all RISC architectures, storing as many parameters in the
call stack is the way to go. Especially when you have 256 64-bit
general purpose registers :-) (Now if only someone implemented a sane
architecture using MMIX as main processor...)
