Function core::arch::x86::_mm_mask_movedup_pd

pub unsafe fn _mm_mask_movedup_pd(
    src: __m128d, 
    k: __mmask8, 
    a: __m128d
) -> __m128d

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

This is supported on (non-crate feature miri-test-libstd or test or doctest) and x86 and target feature avx512f,avx512vl only.

Duplicate even-indexed double-precision (64-bit) floating-point elements from a, and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
