-------------------------------
Resolution: Not A Problem
> [C++] Clean up architecture specific compiler flags
> ---------------------------------------------------
>
> Key: ARROW-2186
> URL: https://issues.apache.org/jira/browse/ARROW-2186
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++
> Reporter: Wes McKinney
> Priority: Major
> Fix For: 0.14.0

>
> I noticed that {{-maltivec}} is being passed to the compiler on Linux, with
> an x86_64 processor. That seemed odd to me. It prompted me to look more
> generally at our compiler flags related to hardware optimizations. We have
> the ability to pass {{-msse3}}, but there is a {{ARROW_USE_SSE}} which is
> only used as a define in some headers. There is {{ARROW_ALTIVEC}}, but no
> option to pass {{-march}}. Nothing related to AVX/AVX2/AVX512. I think this
> could do for an overhaul
