only.Expand description
Shuffle 16-bit integers in the high 64 bits of 128-bit lanes of a using the control in imm8. Store the results in the high 64 bits of 128-bit lanes of dst, with the low 64 bits of 128-bit lanes being copied from from a to dst, using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
