System V.4 places integer and pointer parameters into r3 - r10, and floating point parameters into f1 - f10. Excess parameters (which doesn't happen that often) are put on the stack.

Excuse the dumb question, but why use the stack for "Excess parameters" when the PPC has 32 general purpose and 32 floating point registers?

Please note the last time I've done any 68K ASM was on the "Sinclair QL" many years ago. I have not looked at PPC ASM yet either.

Is this "System V.4" limitation something to do with GCC?

Thanks,
