Function core::arch::x86_64::_mm256_mask_alignr_epi32

pub unsafe fn _mm256_mask_alignr_epi32(
    src: __m256i, 
    k: __mmask8, 
    a: __m256i, 
    b: __m256i, 
    const IMM8: i32
) -> __m256i

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

This is supported on x86-64 and target feature avx512f,avx512vl only.

Concatenate a and b into a 64-byte immediate result, shift the result right by imm8 32-bit elements, and store the low 32 bytes (8 elements) in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
