Function core::arch::x86_64::_mm512_mask2_permutex2var_pd

pub unsafe fn _mm512_mask2_permutex2var_pd(
    a: __m512d,
    idx: __m512i,
    k: __mmask8,
    b: __m512d
) -> __m512d

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

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

Shuffle double-precision (64-bit) floating-point elements in a and b across lanes using the corresponding selector and index in idx, and store the results in dst using writemask k (elements are copied from idx when the corresponding mask bit is not set)
