Function core::arch::x86_64::_mm256_maskz_alignr_epi64

pub unsafe fn _mm256_maskz_alignr_epi64(
    k: __mmask8,
    a: __m256i,
    b: __m256i,
    const IMM8: i32
) -> __m256i

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

Available 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 64-bit elements, and store the low 32 bytes (4 elements) in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
