Function core::arch::x86::_mm_maskz_cvt_roundss_sd

pub unsafe fn _mm_maskz_cvt_roundss_sd(
    k: __mmask8, 
    a: __m128d, 
    b: __m128, 
    const SAE: i32
) -> __m128d

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

This is supported on x86 and target feature avx512f only.

Convert the lower single-precision (32-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.
Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter.
