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

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

Performs a multiplication in GF(2^8) on the packed bytes. The field is in polynomial representation with the reduction polynomial x^8 + x^4 + x^3 + x + 1.

Uses the writemask in k - elements are copied from src if the corresponding mask bit is not set. Otherwise the computation result is written into the result.
