Function core::arch::x86::_mm_mask_shuffle_epi8

pub unsafe fn _mm_mask_shuffle_epi8(
    src: __m128i,
    k: __mmask16,
    a: __m128i,
    b: __m128i
) -> __m128i

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

Available on x86 and target feature avx512bw,avx512vl only.

Shuffle 8-bit integers in a within 128-bit lanes using the control in the corresponding 8-bit element of b, and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
