Apple Darwin on PPC has its own ABI.
The Power Mac G5 processor (PPC970) supported the initial Altivec ISA.
Thanks, David

I thought that you were asking in general. All PowerPC ABI, except the original 32 bit ELF ABI, allow a red zone below the stack pointer. For other architectures, one needs to check each ABI.
Do any of you know what ABI was used on Macs with 64-bit powerpc processors (starting from https://en.wikipedia.org/wiki/Power_Mac_G5, if I understand it correctly?). Probably not worth much effort to support these, but it would be good to at least know if the new assembly files are compatible with that ABI or not.
