Expand description

Multiply the lower half-precision (16-bit) floating-point elements in a and b, and subtract the intermediate result from 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.
