Function core::arch::x86_64::_mm512_mask_permutex_epi64

pub unsafe fn _mm512_mask_permutex_epi64(
    src: __m512i,
    k: __mmask8,
    a: __m512i,
    const MASK: i32
) -> __m512i

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

Available on (x86 or x86-64) and target feature avx512f and x86-64 only.

Shuffle 64-bit integers in a within 256-bit lanes using the control in imm8, and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
