> Since ARROW_USER_SIMD_LEVEL (environment variable) is enough to fix this, do we want to keep ARROW_RUNTIME_SIMD_LEVEL (CMake setting) or not? I will vote +1 to keep ARROW_RUNTIME_SIMD_LEVEL, a SIMD runtime level option at build time should benefit some cases. For example, avx512 is disabled for MINGW build with a HACK. ARROW_RUNTIME_SIMD_LEVEL can be used here. https://github.com/apache/arrow/blob/master/cpp/cmake_modules/SetupCxxFlags.cmake#L55 ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
