As part of a Scalar ISA this not practical. A compromise is to cut the registers required -by half. +by half, placing it on-par with `lq`, `stq` and Indexed +Load-with-update instructions. When part of the Scalar Power ISA (not SVP64 Vectorised) mv.swiz and fmv.swiz operate on four 32-bit quantities, reducing this instruction to a feasible
