Function core::arch::x86::_mm_mask_move_sd

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

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

This is supported on x86 and target feature avx512f only.

Move the lower double-precision (64-bit) floating-point element from b to the lower element of dst using writemask k (the element is copied from src when mask bit 0 is not set), and copy the upper element from a to the upper element of dst.
