Does anyone have an ARM machine that they would like to use for testing sha vectorizations and native sha extensions?

For my past sins I was given a Mac M1. I have Linux on it now.

Let me know what benchmarks/tests you want to run. I can try.

Ok, I'll let you know. I had grok translate my intrinsics macros from intel into arm equivalents, and it thinks it will be drop-in equivalent. Fingers crossed.

I just learned that ARM SVE gives us up to 4 concurrent native SHA hashes via native sha in 512 bits (128 each), which should be 4x faster than SHANI.
