Function core::arch::x86_64::_mm_mask2_permutex2var_epi8

pub unsafe fn _mm_mask2_permutex2var_epi8(
    a: __m128i,
    idx: __m128i,
    k: __mmask16,
    b: __m128i

🔬This is a nightly-only experimental API. (stdsimd #48556)

Available on (x86 or x86-64) and target feature avx512vbmi,avx512vl and 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).
