Function core::arch::x86::_mm256_maskz_alignr_epi8

pub unsafe fn _mm256_maskz_alignr_epi8(
    k: __mmask32, 
    a: __m256i, 
    b: __m256i, 
    const IMM8: i32
) -> __m256i

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

Available on x86 and target feature avx512bw,avx512vl only.

Concatenate pairs of 16-byte blocks in a and b into a 32-byte temporary result, shift the result right by imm8 bytes, and store the low 16 bytes in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
