[Openmcl-devel] M1 Port - Why PPC64 rather than the Arm32 port?

The 32-bit Arm architecture is very different from the 64-bit architecture and isn’t a good starting point.

The better question is why PPC64 instead of x86-64? The main reason is that, like Arm64, PPC64 has 32 registers vs. 16 for x86-64.
