pub unsafe fn _mm256_mask_permutex2var_epi8(
    a: __m256i,
    k: u32,
    idx: __m256i,
    b: __m256i,

🔬This is a nightly-only experimental API. (stdarch_x86_avx512)

Available on x86-64 only.

Shuffle 8-bit integers in a and b across lanes using the corresponding selector and index in idx, and store the results in dst using writemask k (elements are copied from a when the corresponding mask bit is not set).
