Function core::arch::x86_64::_mm_maskz_add_sd

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

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

This is supported on x86-64 and target feature avx512f only.

Add the lower double-precision (64-bit) floating-point element in a and b, store the result in the lower element of dst using zeromask k (the element is zeroed out when mask bit 0 is not set), and copy the upper element from a to the upper element of dst.
