2825 (xxspltib_<mode>_split): New insn to load up constants with
2826 XXSPLTIB and a sign extend instruction.
2827 (vsx_mov<mode>): Replace single move that handled all vector types
2828 with separate 32-bit and 64-bit moves. Combine the movti_<bit>
2829 moves (when -mvsx-timode is in effect) into the main vector
2830 moves. Eliminate separate moves for <VSr> <VSa>, where the
2831 preferred register class (<VSr>) is listed first, and the
2832 secondary register class (<VSa>) is listed second with a '?' to
2833 discourage use. Prefer loading 0/-1 in any VSX register for ISA
2834 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
2835 that if the register was involved in a slow operation, the
2836 clear/set operation does not wait for the slow operation to
2837 finish. Adjust the length attributes for 32-bit mode. Use
2838 rs6000_output_move_128bit and drop the use of the string
2839 instructions for 32-bit movti when -mvsx-timode is in effect. Use
2840 spacing so that the alternatives and attributes don't generate
2841 long lines, and put things in columns, so that it is easier to
2842 match up the operands and attributes with the insn alternatives.
