9569 moves. Eliminate separate moves for <VSr> <VSa>, where the
9570 preferred register class (<VSr>) is listed first, and the
9571 secondary register class (<VSa>) is listed second with a '?' to
9572 discourage use. Prefer loading 0/-1 in any VSX register for ISA
9573 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
9574 that if the register was involved in a slow operation, the
9575 clear/set operation does not wait for the slow operation to
9576 finish. Adjust the length attributes for 32-bit mode. Use
9577 rs6000_output_move_128bit and drop the use of the string
9578 instructions for 32-bit movti when -mvsx-timode is in effect. Use
9579 spacing so that the alternatives and attributes don't generate
9580 long lines, and put things in columns, so that it is easier to
9581 match up the operands and attributes with the insn alternatives.
