Comment 5 for bug 2059910

> Apparently the emulation doesn't support AVX instructions.

A web search confirms that, but it's still unclear to me whether Apple's Rosetta-2 emulation supports SSE4.2. It might not. I found hints that it supports SSE2, but that's not what I'm after.

Can anyone get the "CPUID" flags from the emulation and post them here? There's supposed to be a "sysctl" command for this, but I can't tell whether it works in emulation mode:

    sysctl -a | grep machdep.cpu.features

On Linux, there's the "cpuid" command or "lscpu", or you can read from "/proc/cpuinfo".
