--------------------------------
Summary: [Dev][Archery] Arm NEON disabled in C++ benchmark
Key: ARROW-15004
URL: https://issues.apache.org/jira/browse/ARROW-15004
Project: Apache Arrow
Issue Type: Bug
Components: C++, Developer Tools
Reporter: Yibo Cai
Assignee: Yibo Cai
I find NEON code is always skipped by {{archery benchmark ...}} even if run on
Arm machines.
It's because ARROW_SIMD_LEVEL is fixed to SSE4_2 in archery:
https://github.com/apache/arrow/blob/master/dev/archery/archery/lang/cpp.py#L245
We should use "DEFAULT" simd level which is added in a recent pr to address
different archs.
