3810 instruction and possibly with a sign extension.
3811 (output_vec_const_move): Add support for XXSPLTIB. If we are
3812 loading up 0/-1 into Altivec registers, prefer using VSPLTISW
3813 instead of XXLXOR/XXLORC.
3814 (rs6000_expand_vector_init): Add support for ISA 3.0 word splat
3816 (rs6000_legitimize_reload_address): Likewise.

3830 (vsx_mov<mode>): Replace single move that handled all vector types
3831 with separate 32-bit and 64-bit moves. Combine the movti_<bit>
3832 moves (when -mvsx-timode is in effect) into the main vector
3833 moves. Eliminate separate moves for <VSr> <VSa>, where the
3834 preferred register class (<VSr>) is listed first, and the
3835 secondary register class (<VSa>) is listed second with a '?' to
3836 discourage use. Prefer loading 0/-1 in any VSX register for ISA
3837 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
3838 that if the register was involved in a slow operation, the
3839 clear/set operation does not wait for the slow operation to
3840 finish. Adjust the length attributes for 32-bit mode. Use
3841 rs6000_output_move_128bit and drop the use of the string
3842 instructions for 32-bit movti when -mvsx-timode is in effect. Use
3843 spacing so that the alternatives and attributes don't generate
3844 long lines, and put things in columns, so that it is easier to
3845 match up the operands and attributes with the insn alternatives.
