[jira] [Created] (ARROW-18162) [C++] Add Arm SVE compiler options

Yibo Cai created ARROW-18162:
--------------------------------

             Summary: [C++] Add Arm SVE compiler options
                 Key: ARROW-18162
                 URL: https://issues.apache.org/jira/browse/ARROW-18162
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Yibo Cai
            Assignee: Yibo Cai


{{xsimd}} 9.0+ supports Arm SVE (fixed size). Some additional compiler options are required to enable SVE.

Per my test on Amazon Graviton3 (SVE-256). SVE256 performs much better than NEON for some cases. E.g., utf8 benchmark {{ValidateLargeAscii}} improves from *38.6* (NEON) to *51.5* (SVE256) GB/s.
