Wes McKinney closed ARROW-2186. ------------------------------- 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 -- This message was sent by Atlassian JIRA (v7.6.3#76005)
