_mm_mask3_fmadd_sh in core::arch::x86 - Rust
Description: 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.
