Function core::arch::x86_64::_mm512_maskz_alignr_epi64

pub unsafe fn _mm512_maskz_alignr_epi64(
    k: __mmask8, 
    a: __m512i, 
    b: __m512i, 
    const IMM8: i32
) -> __m512i

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

Available on x86-64 and target feature avx512f only.

Concatenate a and b into a 128-byte immediate result, shift the result right by imm8 64-bit elements, and stores the low 64 bytes (8 elements) in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
