If it builds with Meson, you're good.
The latest cfbot build for this seems to indicate that at least newer MSVC knows AVX512 intrinsics without any special compiler flags [0], so maybe what I had in v14 is good enough. A previous version of the patch set [1] had the following lines: + if host_system == 'windows' + test_flags = ['/arch:AVX512'] + endif I'm not sure if this is needed for older MSVC or something else. IIRC I couldn't find any other examples of this sort of thing in the meson scripts, either. Paul, do you recall why you added this?
