#### 30.6.2. ARMv8 Advanced SIMD and floating-point support

The ARMv8 architecture reference manual specifies floating point and SIMD support in the main architecture at A1.5 "Advanced SIMD and floating-point support".

The feature is often refered to simply as "SIMD&FP" throughout the manual.

The Linux kernel shows `/proc/cpuinfo` compatibility as `neon`, which is yet another intermediate name that came up at some point, see: Section 30.6.2.2, “ARM NEON”.
