genmatch.c (::gen_transform): Add capture_info and expand_compares arguments.

2014-11-12  Richard Biener  <rguenther@suse.de>

	* genmatch.c (::gen_transform): Add capture_info and
	expand_compares arguments.
	(struct expr): Add is_generic flag.
	(lower_cond): New functions lowering [VEC_]COND_EXPR
	conditions to a GENERIC and a GIMPLE variant.
	(lower): Call lower_cond.
	(cmp_operand): Also compare the is_generic flag.
	(capture_info::cinfo): Add cond_expr_cond_p flag.
	(capture_info::capture_info): Pass down whether the
	expression argument is a COND_EXPR condition.
	(capture_info::walk_match): Likewise, mark captures
	capturing COND_EXPR conditions with cond_expr_cond_p.
	(expr::gen_transform): Pass down whether we need to
	expand compares from COND_EXPR conditions.
	(capture::gen_transform): Expand compares substituted
	from COND_EXPR conditions into non-COND_EXPR conditions.
	(dt_operand::gen_gimple_expr): Handle explicitely marked
	GENERIC expressions as generic.
	(dt_simplify::gen): Pass whether we need to expand
	conditions to gen_transform.  Handle capture results
	which are from COND_EXPR conditions.
	(main): Pass gimple flag down to lower.
