Function tracing::stdlib::arch::x86_64::_mm_mask_cvtss_sd

pub unsafe fn _mm_mask_cvtss_sd(
    src: __m128d,
    k: u8,
    a: __m128d,
    b: __m128,
) -> __m128d

🔬This is a nightly-only experimental API. (stdarch_x86_avx512 #111137)

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