Thanks. I guess I was thinking that any patents on the instruction in the original article and of FP behaviour would predate 64-bit, but you're right that there could be relevant patents on x86-64.

Thinking aloud, I wonder if AVX 512 is translated?

AVX instructions are not supported. See here: https://medium.com/macoclock/m1-rosetta-2-limitation-illegal...

Thanks! Presumably most retail x86-64 applications will have an execution path that avoids AVX?

Intel still sells x86_64 CPUs without AVX. See Jasper Lake and Comet Lake Celeron/Pentium.
