536 that if the register was involved in a slow operation, the

538 finish. Adjust the length attributes for 32-bit mode. Use
539 rs6000_output_move_128bit and drop the use of the string
540 instructions for 32-bit movti when -mvsx-timode is in effect. Use
541 spacing so that the alternatives and attributes don't generate
