That is not possible with the x86 SIMD instructions Actually, when the code is expressed using "portable intrinsics" (https://github.com/google/highway https://github.com/google/highway), the source code looks the same but compiles to SSE4/AVX2/AVX-512 and NEON,SVE,SVE2 and RISC-V V instructions. Disclosure: I am the main author of this library.
