Both floating-point and NEON are required in all standard ARMv8 implementations. Theoretically though specialized markets can support no NEON or floating-point at all. Source: https://developer.arm.com/docs/den0024/latest/aarch64-floating-point-and-neon On the other hand the base procedure call standard for Aarch64 "assumes the availability of the vector registers for passing floating-point and SIMD arguments". Further "the Arm 64-bit architecture defines two mandatory register banks: a general-purpose register bank which can be used for scalar integer processing and pointer arithmetic; and a SIMD and Floating-Point register bank". Source: https://developer.arm.com/docs/ihi0055/latest/procedure-call-standard-for-the-arm-64-bit-architecture This makes customization of Aarch64 with no NEON instruction set available so unlikely that we can consider them a feature of the generic family. |
