１．２ About the Scalable Vector Extensionのところにこう書かれてる
SVE is an optional extension to the ARMv8-A architecture, with a base requirement of ARMv8.2-A.
SVE complements and does not replace ARMv8-A Advanced SIMD and floating-point functionality.
If SVE is implemented, all SVE instructions are mandatory
and the ARMv8.2-FP16 half-precision floating-point
and the ARMv8.3-A AArch64 complex number instructions must be implemented.
