17288 moves (when -mvsx-timode is in effect) into the main vector
17289 moves. Eliminate separate moves for <VSr> <VSa>, where the
17290 preferred register class (<VSr>) is listed first, and the
17291 secondary register class (<VSa>) is listed second with a '?' to
17292 discourage use. Prefer loading 0/-1 in any VSX register for ISA
17293 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
17294 that if the register was involved in a slow operation, the
17295 clear/set operation does not wait for the slow operation to
17296 finish. Adjust the length attributes for 32-bit mode. Use
17297 rs6000_output_move_128bit and drop the use of the string
17298 instructions for 32-bit movti when -mvsx-timode is in effect. Use
17299 spacing so that the alternatives and attributes don't generate
17300 long lines, and put things in columns, so that it is easier to
17301 match up the operands and attributes with the insn alternatives.
