4259 * config/rs6000/rs6000.c (xxspltib_constant_p): New function to

4261 instruction and possibly with a sign extension.
4262 (output_vec_const_move): Add support for XXSPLTIB. If we are
4263 loading up 0/-1 into Altivec registers, prefer using VSPLTISW
4264 instead of XXLXOR/XXLORC.

4282 with separate 32-bit and 64-bit moves. Combine the movti_<bit>
4283 moves (when -mvsx-timode is in effect) into the main vector
4284 moves. Eliminate separate moves for <VSr> <VSa>, where the
4285 preferred register class (<VSr>) is listed first, and the
4286 secondary register class (<VSa>) is listed second with a '?' to
4287 discourage use. Prefer loading 0/-1 in any VSX register for ISA
4288 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
4289 that if the register was involved in a slow operation, the
4290 clear/set operation does not wait for the slow operation to
4291 finish. Adjust the length attributes for 32-bit mode. Use
4292 rs6000_output_move_128bit and drop the use of the string
4293 instructions for 32-bit movti when -mvsx-timode is in effect. Use
4294 spacing so that the alternatives and attributes don't generate
4295 long lines, and put things in columns, so that it is easier to
4296 match up the operands and attributes with the insn alternatives.
4297 (vsx_mov<mode>_64bit): Likewise.
