3635 with separate 32-bit and 64-bit moves. Combine the movti_<bit>
3636 moves (when -mvsx-timode is in effect) into the main vector
3637 moves. Eliminate separate moves for <VSr> <VSa>, where the
3638 preferred register class (<VSr>) is listed first, and the
3639 secondary register class (<VSa>) is listed second with a '?' to
3640 discourage use. Prefer loading 0/-1 in any VSX register for ISA
3641 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
3642 that if the register was involved in a slow operation, the
3643 clear/set operation does not wait for the slow operation to
3644 finish. Adjust the length attributes for 32-bit mode. Use
3645 rs6000_output_move_128bit and drop the use of the string
3646 instructions for 32-bit movti when -mvsx-timode is in effect. Use
3647 spacing so that the alternatives and attributes don't generate
3648 long lines, and put things in columns, so that it is easier to
3649 match up the operands and attributes with the insn alternatives.
