-----------------------------------
Summary: [C++] Add SSE4.2-accelerated hash kernels and use if host
CPU supports
Key: ARROW-1822
URL: https://issues.apache.org/jira/browse/ARROW-1822
Project: Apache Arrow
Issue Type: New Feature
Components: C++
Reporter: Wes McKinney
SSE4.2 has CRC32 intrinsics that can be used to compute hash values. It seems
it may be acceptable to use {{-msse4.2}} on isolated compilation units, but if
this object code is used on a machine without support for the SIMD
instructions, then it will crash
