New Revision: 179376

Log:
Add sparc VIS 2.0 builtins, intrinsics, and option to control them.

gcc/

	* config/sparc/sparc.opt (VIS2): New option.
	* doc/invoke.texi: Document it.
	* config/sparc/sparc.md (UNSPEC_EDGE8N, UNSPEC_EDGE8LN,
	UNSPEC_EDGE16N, UNSPEC_EDGE16LN, UNSPEC_EDGE32N,
	UNSPEC_EDGE32LN, UNSPEC_BSHUFFLE): New unspecs.
	(define_attr type): New insn type 'edgen'.
	(bmask<P:mode>_vis, bshuffle<V64I:mode>_vis, edge8n<P:mode>_vis,
	edge8ln<P:mode>_vis, edge16n<P:mode>_vis, edge16ln<P:mode>_vis,
	edge32n<P:mode>_vis, edge32ln<P:mode>_vis): New insn VIS 2.0
	patterns.
	* niagara.md: Handle edgen.
	* niagara2.md: Likewise.
	* ultra1_2.md: Likewise.
	* ultra3.md: Likewise.
	* config/sparc/sparc-c.c (sparc_target_macros): Define __VIS__
	to 0x200 when TARGET_VIS2.
	* config/sparc/sparc.c (sparc_option_override): Set MASK_VIS2 by
	default when targetting capable cpus.  TARGET_VIS2 implies
	TARGET_VIS, clear and it when TARGET_FPU is disabled.
	(sparc_vis_init_builtins): Emit new VIS 2.0 builtins.
	(sparc_expand_builtin): Fix predicate indexing when builtin returns
	void.
	(sparc_fold_builtin): Do not eliminate bmask when result is ignored.
	* config/sparc/visintrin.h (__vis_bmask, __vis_bshuffledi,
	__vis_bshufflev2si, __vis_bshufflev4hi, __vis_bshufflev8qi,
	__vis_edge8n, __vis_edge8ln, __vis_edge16n, __vis_edge16ln,
	__vis_edge32n, __vis_edge32ln): New VIS 2.0 interfaces.
	* doc/extend.texi: Document new VIS 2.0 builtins.

gcc/testsuite/

	* gcc.target/sparc/bmaskbshuf.c: New test.
	* gcc.target/sparc/edgen.c: New test.
