Wes McKinney created ARROW-2186:
-----------------------------------
Summary: [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
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
