4256 * config/rs6000/constraints.md (wE constraint): New constraint
4257 for a vector constant that can be loaded with XXSPLTIB.
4258 (wM constraint): New constraint for a vector constant of a 1's.
4259 (wS constraint): New constraint for a vector constant that can be
4260 loaded with XXSPLTIB and a vector sign extend instruction.
4261 * config/rs6000/predicates.md (xxspltib_constant_split): New
4262 predicates for wE/wS constraints.
4263 (xxspltib_constant_nosplit): Likewise.
4264 (easy_vector_constant): Add support for constants that can be
4265 loaded via XXSPLTIB.
4266 (all_ones_constant): New predicate for vector constant with all
4268 (splat_input_operand): Add support for ISA 3.0 word splat operations.
4269 * config/rs6000/rs6000.c (xxspltib_constant_p): New function to
4270 return if a constant can be loaded with the ISA 3.0 XXSPLTIB
4271 instruction and possibly with a sign extension.
4272 (output_vec_const_move): Add support for XXSPLTIB. If we are
4273 loading up 0/-1 into Altivec registers, prefer using VSPLTISW
4274 instead of XXLXOR/XXLORC.
4275 (rs6000_expand_vector_init): Add support for ISA 3.0 word splat
4277 (rs6000_legitimize_reload_address): Likewise.
4278 (rs6000_output_move_128bit): Use output_vec_const_move to emit
4280 * config/rs6000/vsx.md (VSX_M): Add TImode (if -mvsx-timode) and
4281 combine VSX_M and VSX_M2 into one iterator.
4283 (VSINT_84): New iterators for loading constants with XXSPLTIB.
4284 (VSINT_842): Likewise.
4285 (UNSPEC_VSX_SIGN_EXTEND): New UNSPEC.
4286 (xxspltib_v16qi): New insns to load up constants with the ISA 3.0
4287 XXSPLTIB instruction.
4288 (xxspltib_<mode>_nosplit): Likewise.
4289 (xxspltib_<mode>_split): New insn to load up constants with
4290 XXSPLTIB and a sign extend instruction.
4291 (vsx_mov<mode>): Replace single move that handled all vector types
4292 with separate 32-bit and 64-bit moves. Combine the movti_<bit>
4293 moves (when -mvsx-timode is in effect) into the main vector
4294 moves. Eliminate separate moves for <VSr> <VSa>, where the
4295 preferred register class (<VSr>) is listed first, and the
4296 secondary register class (<VSa>) is listed second with a '?' to
4297 discourage use. Prefer loading 0/-1 in any VSX register for ISA
4298 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
4299 that if the register was involved in a slow operation, the
4300 clear/set operation does not wait for the slow operation to
4301 finish. Adjust the length attributes for 32-bit mode. Use
4302 rs6000_output_move_128bit and drop the use of the string
4303 instructions for 32-bit movti when -mvsx-timode is in effect. Use
4304 spacing so that the alternatives and attributes don't generate
4305 long lines, and put things in columns, so that it is easier to
4306 match up the operands and attributes with the insn alternatives.
4307 (vsx_mov<mode>_64bit): Likewise.
4308 (vsx_mov<mode>_32bit): Likewise.

4315 (vector fusion peepholes): Use VSX_M instead of VSX_M2.

4317 extend vector elements.
4318 (vsx_sign_extend_hi_<mode>): Likewise.
