- 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
- that if the register was involved in a slow operation, the
- clear/set operation does not wait for the slow operation to
- finish. Adjust the length attributes for 32-bit mode. Use
- rs6000_output_move_128bit and drop the use of the string
- instructions for 32-bit movti when -mvsx-timode is in effect. Use
- spacing so that the alternatives and attributes don't generate
