### Describe the enhancement requested PyArrow and R arrow have user-facing functions that call into Arrow C++'s `arrow::GetRuntimeInfo()` to report on build and runtime SIMD support: https://github.com/apache/arrow/blob/4a4d5802bf501dfedb98785587aba53396a46dee/cpp/src/arrow/config.cc#L74-L80 `GetRuntimeInfo` calls into `MakeSimdLevelString` to populate a `RuntimeInfo` object. On ARM-based systems, "none" is reported for both SIMD levels which I think is caused by a there being no branch for `CpuInfo::ASIMD`: https://github.com/apache/arrow/blob/f710ac52b049806515a14445b242c3ec819fb99d/cpp/src/arrow/config.cc#L52-L64 1. Should we add a branch for `CpuInfo::ASIMD`? 2. If so, would it make more sense to call it ASIMD or NEON? They're [related but slightly different concepts](https://developer.arm.com/documentation/dht0002/a/Introducing-NEON/What-is-NEON-) and I'm not sure what language users will be most familiar with and which makes more sense alongside other values. ### Component(s) C++ -- This is an automated message from the Apache Git Service.
