well, if you need to pass so many parameters, then x86 32 bit
registers can not cope with that. You only have EAX, EBX, ECX, EDX,
ESI, EDI as far as I could remember.

probably in 64 bit, registers is way more so it's still possible to
put them in registers, which is of course the fastest way to access
them.
