Re: [DISCUSS][C++] Strategies for SIMD cross-compilation?

Re: [C++] adopting an SIMD library - xsimd

Thanks for comments on the SIMD related PR: https://github.com/apache/arrow/pull/9424. Agree to adopt the *xsimd *as the SIMD wrapper library for Arrow to avoid a large maintenance burden. It makes sense. It seems *ximd *is designed for mathematics calculating and it lacks the functions like bit/b
