6067 instruction and possibly with a sign extension.
6068 (output_vec_const_move): Add support for XXSPLTIB. If we are
6069 loading up 0/-1 into Altivec registers, prefer using VSPLTISW
6070 instead of XXLXOR/XXLORC.

6088 with separate 32-bit and 64-bit moves. Combine the movti_<bit>
6089 moves (when -mvsx-timode is in effect) into the main vector
6090 moves. Eliminate separate moves for <VSr> <VSa>, where the
6091 preferred register class (<VSr>) is listed first, and the
6092 secondary register class (<VSa>) is listed second with a '?' to
6093 discourage use. Prefer loading 0/-1 in any VSX register for ISA
6094 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
6095 that if the register was involved in a slow operation, the
6096 clear/set operation does not wait for the slow operation to
6097 finish. Adjust the length attributes for 32-bit mode. Use
6098 rs6000_output_move_128bit and drop the use of the string
6099 instructions for 32-bit movti when -mvsx-timode is in effect. Use
6100 spacing so that the alternatives and attributes don't generate
6101 long lines, and put things in columns, so that it is easier to
6102 match up the operands and attributes with the insn alternatives.
