Description

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.
