523 * config/rs6000/rs6000.c (xxspltib_constant_p): New function to
524 return if a constant can be loaded with the ISA 3.0 XXSPLTIB
525 instruction and possibly with a sign extension.
526 (output_vec_const_move): Add support for XXSPLTIB. If we are
527 loading up 0/-1 into Altivec registers, prefer using VSPLTISW
528 instead of XXLXOR/XXLORC.
529 (rs6000_expand_vector_init): Add support for ISA 3.0 word splat
531 (rs6000_legitimize_reload_address): Likewise.

545 (vsx_mov<mode>): Replace single move that handled all vector types
546 with separate 32-bit and 64-bit moves. Combine the movti_<bit>
547 moves (when -mvsx-timode is in effect) into the main vector
548 moves. Eliminate separate moves for <VSr> <VSa>, where the
549 preferred register class (<VSr>) is listed first, and the
550 secondary register class (<VSa>) is listed second with a '?' to
551 discourage use. Prefer loading 0/-1 in any VSX register for ISA
552 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
553 that if the register was involved in a slow operation, the
554 clear/set operation does not wait for the slow operation to
555 finish. Adjust the length attributes for 32-bit mode. Use
556 rs6000_output_move_128bit and drop the use of the string
557 instructions for 32-bit movti when -mvsx-timode is in effect. Use
558 spacing so that the alternatives and attributes don't generate
559 long lines, and put things in columns, so that it is easier to
560 match up the operands and attributes with the insn alternatives.
