Expand description

Multiply the lower half-precision (16-bit) floating-point elements in a and b, and subtract packed elements in c from the intermediate result. 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 7 packed elements from a to the upper elements of dst.
