Options

Add support for the VIS3 addxc instruction. 

gcc/

	* config/sparc/sparc.md (snedi_special): Only match when not VIS3.
	(*snedi_zero): Likewise.
	(*snedi_zero_trunc): Likewise.
	(snedi_special_vis3): New expander.
	(*snedi_zero_vis3): New insn.
	(*snedi_zero_trunc_vis3): Likewise.
	(*sltu_insn_vis3): Likewise.
	(*sltu_insn_vis3_trunc): Likewise.
	(addxc): Likewise.
	(*addxc_trunc_sp64_vis3): Likewise.
	* config/sparc/sparc.c (emit_scc_insn): When VIS3 use the
	gen_snedi_special_vis3 expander, and try GTU/LTU addx based
	sequences on DImode values.

gcc/testsuite/

	* gcc.target/sparc/setcc-3.c: New test.
