--------------------------------
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.
