Function core::arch::x86::_mm_maskz_cvtsd_ss

pub unsafe fn _mm_maskz_cvtsd_ss(k: __mmask8, a: __m128, b: __m128d) -> __m128

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

Available on x86 and target feature avx512f only.

Convert the lower double-precision (64-bit) floating-point element in b to a single-precision (32-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 3 packed elements from a to the upper elements of dst.
