1464 moves (when -mvsx-timode is in effect) into the main vector
1465 moves. Eliminate separate moves for <VSr> <VSa>, where the
1466 preferred register class (<VSr>) is listed first, and the
1467 secondary register class (<VSa>) is listed second with a '?' to
1468 discourage use. Prefer loading 0/-1 in any VSX register for ISA
1469 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
1470 that if the register was involved in a slow operation, the
1471 clear/set operation does not wait for the slow operation to
1472 finish. Adjust the length attributes for 32-bit mode. Use
1473 rs6000_output_move_128bit and drop the use of the string
1474 instructions for 32-bit movti when -mvsx-timode is in effect. Use
1475 spacing so that the alternatives and attributes don't generate
1476 long lines, and put things in columns, so that it is easier to
1477 match up the operands and attributes with the insn alternatives.
