Expand description

Multiply packed unsigned 52-bit integers in each 64-bit element of `b` and `c` to form a 104-bit intermediate result. Add the high 52-bit unsigned integer from the intermediate result with the corresponding unsigned 64-bit integer in `a`, and store the results in `dst` using writemask `k` (elements are zeroed out when the corresponding mask bit is not set).
