18607 with separate 32-bit and 64-bit moves. Combine the movti_<bit>
18608 moves (when -mvsx-timode is in effect) into the main vector
18609 moves. Eliminate separate moves for <VSr> <VSa>, where the
18610 preferred register class (<VSr>) is listed first, and the
18611 secondary register class (<VSa>) is listed second with a '?' to
18612 discourage use. Prefer loading 0/-1 in any VSX register for ISA
18613 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
18614 that if the register was involved in a slow operation, the
18615 clear/set operation does not wait for the slow operation to
18616 finish. Adjust the length attributes for 32-bit mode. Use
18617 rs6000_output_move_128bit and drop the use of the string
18618 instructions for 32-bit movti when -mvsx-timode is in effect. Use
18619 spacing so that the alternatives and attributes don't generate
18620 long lines, and put things in columns, so that it is easier to
18621 match up the operands and attributes with the insn alternatives.
