3333 instruction and possibly with a sign extension.
3334 (output_vec_const_move): Add support for XXSPLTIB. If we are
3335 loading up 0/-1 into Altivec registers, prefer using VSPLTISW
3336 instead of XXLXOR/XXLORC.
3337 (rs6000_expand_vector_init): Add support for ISA 3.0 word splat
3339 (rs6000_legitimize_reload_address): Likewise.

3353 (vsx_mov<mode>): Replace single move that handled all vector types
3354 with separate 32-bit and 64-bit moves. Combine the movti_<bit>
3355 moves (when -mvsx-timode is in effect) into the main vector
3356 moves. Eliminate separate moves for <VSr> <VSa>, where the
3357 preferred register class (<VSr>) is listed first, and the
3358 secondary register class (<VSa>) is listed second with a '?' to
3359 discourage use. Prefer loading 0/-1 in any VSX register for ISA
3360 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
3361 that if the register was involved in a slow operation, the
3362 clear/set operation does not wait for the slow operation to
3363 finish. Adjust the length attributes for 32-bit mode. Use
3364 rs6000_output_move_128bit and drop the use of the string
3365 instructions for 32-bit movti when -mvsx-timode is in effect. Use
3366 spacing so that the alternatives and attributes don't generate
3367 long lines, and put things in columns, so that it is easier to
3368 match up the operands and attributes with the insn alternatives.
