Function _mm_mask3_fmadd_sh

pub fn _mm_mask3_fmadd_sh(a: __m128h, b: __m128h, c: __m128h, k: u8) -> __m128h

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

Multiply the lower half-precision (16-bit) floating-point elements in a and b, and add the intermediate result to the lower element in c. Store the result in the lower element of dst using writemask k (the element is copied from c when the mask bit 0 is not set), and copy the upper 7 packed elements from c to the upper elements of dst.
