and x86 only.Expand description
Multiply packed half-precision (16-bit) floating-point elements in a and b, alternatively add and subtract packed elements in c to/from the intermediate result, and store the results in dst using zeromask k (the element is zeroed out when the corresponding mask bit is not set).
