Function core::arch::x86::_mm256_mask2_permutex2var_pd

pub unsafe fn _mm256_mask2_permutex2var_pd(
    a: __m256d,
    idx: __m256i,
    k: __mmask8,
    b: __m256d,

🔬This is a nightly-only experimental API. (stdarch_x86_avx512 #111137)

Available on (x86 or x86-64) and target feature avx512f,avx512vl and x86 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)
