After some research on the code history, it appears to me that: 1. The naming similarity between `ARROW_SIMD_LEVEL`/`ARROW_RUNTIME_SIMD_LEVEL` and `ARROW_HAVE_* `/`ARROW_HAVE_RUNTIME_*` seems to be a (unfortunate?) coincidence. They don't really relate to each other. 2. The cmake option `ARROW_RUNTIME_SIMD_LEVEL` seems to be introduced in https://github.com/apache/arrow/pull/8049 to solely tailor the SIMD level specified by `ARROW_SIMD_LEVEL` at compile time. 3. The `ARROW_HAVE_RUNTIME_*` (introduced in https://github.com/apache/arrow/pull/7607) macros seem to be duplicated with `ARROW_HAVE_*` (introduced in https://github.com/apache/arrow/pull/6794) and need some cleanup. @pitrou I'm not familiar with the full story so please correct me if I get anything wrong. -- This is an automated message from the Apache Git Service.
