> [~jeroenooms] hit a crash in the "sum" compute kernel using the R package on
> a new M1 machine running the rosetta emulator:
> https://gist.github.com/jeroen/c60548b29ff7f6807a6554799bd01cb7
> According to
> https://developer.apple.com/documentation/apple_silicon/about_the_rosetta_translation_environment,
> we should be checking sysctlbyname for AVX* capabilities, but we are not. We
> only use that function in
> https://github.com/apache/arrow/blob/master/cpp/src/arrow/util/cpu_info.cc#L350-L359
> to check cpu cache size.
> This may also explain a crash we observed previously on a very old macOS CRAN
> machine.
> I think we should to resolve this before the 3.0 release if possible, in
> order to avoid bug reports as more people get M1s.
