Function _mm_maskz_cvtsh_sd

pub unsafe fn _mm_maskz_cvtsh_sd(k: __mmask8, a: __m128d, b: __m128h) -> __m128d

🔬This is a nightly-only experimental API. (stdarch_x86_avx512_f16 #127213)

Available on (x86 or x86-64) and target feature avx512fp16 and x86-64 only.

Convert the lower half-precision (16-bit) floating-point element in b to a double-precision (64-bit) floating-point element, 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.
