🔬 This is a nightly-only experimental API. (stdsimd)

This is supported with target feature avx512gfni,avx512bw,avx512vl only.

Performs an affine transformation on the packed bytes in x. That is computes a*x+b over the Galois Field 2^8 for each packed byte with a being a 8x8 bit matrix and b being a constant 8-bit immediate value. Each pack of 8 bytes in x is paired with the 64-bit word at the same position in a.
