Function core::arch::x86_64::_mm_maskz_alignr_epi8

pub unsafe fn _mm_maskz_alignr_epi8<const IMM8: i32>(
    k: __mmask16, 
    a: __m128i, 
    b: __m128i
) -> __m128i

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

This is supported on x86-64 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).
