Function core::arch::x86_64::_mm_mask_cvtsd_ss

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

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

Available on (x86 or x86-64) and target feature avx512f and x86-64 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 writemask k (the element is copied from src when mask bit 0 is not set), and copy the upper 3 packed elements from a to the upper elements of dst.
