    In my Windows 11/ARM64 VM running in Parallels on M1 any Windows x64 code that calls AVX will fail with an illegal instruction.
    This seems to be a limitation of the x86/x64 emulator built into Windows 11 that also applies to Rosetta. I assume this is because emulating AVX is just not feasible on the current ARM architecture.
