Hi, Thanks to pravindra's patch [1], Gandiva loop vectorization is okay now.
Will Gandiva detects CPU feature at runtime? My test CPU supports sse to avx2, but I only see "target-features"="+fxsr,+mmx,+sse,+sse2,+x87" in IR, and final code doesn't leverage registers longer than 128. [1] https://github.com/apache/arrow/pull/6019
