DUPQ Broadcast indexed element within each quadword vector segment (unpredicated) Unconditionally broadcast the indexed element within each 128-bit source vector segment to all elements of the corresponding destination vector segment. This instruction is unpredicated. The immediate element index is in the range of 0 to 15 (bytes), 7 (halfwords), 3 (words) or 1 (doublewords).
