> {{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.
