Function core::arch::x86_64::_mm256_mask_permutex_pd

pub unsafe fn _mm256_mask_permutex_pd(
    src: __m256d, 
    k: __mmask8, 
    a: __m256d, 
    const MASK: i32
) -> __m256d

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

Available on x86-64 and target feature avx512f,avx512vl only.

Shuffle double-precision (64-bit) floating-point elements 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).
