Ian Cook commented on ARROW-12587:
----------------------------------
When I build libarrow with
{code:java}
HOMEBREW_NO_AUTO_UPDATE=1 brew install --build-from-source
./apache-arrow.rb{code}
using {{apache-arrow.rb}} downloaded from
[https://github.com/Homebrew/homebrew-core/blob/master/Formula/apache-arrow.rb|https://github.com/Homebrew/homebrew-core/blob/master/Formula/apache-arrow.rb,],
{{arrow_info()}} reports:
{code:java}
Runtime:
SIMD Level avx2
Detected SIMD Level avx2{code}
The same happens if I modify {{apache-arrow.rb}} to and add
{{-DARROW_RUNTIME_SIMD_LEVEL=MAX}} or {{-DARROW_RUNTIME_SIMD_LEVEL=AVX2}}.
So it seems like there is an AVX512 instruction being executed when it
shouldn't.
