2014-10-24  Richard Biener  <rguenther@suse.de>

	* genmatch.c (expr::gen_transform): Use fold_buildN_loc
	and build_call_expr_loc.
	(dt_simplify::gen): Drop non_lvalue for GIMPLE, use
	non_lvalue_loc to build it for GENERIC.
	(decision_tree::gen_generic): Add location argument to
	generic_simplify prototype.
	(capture_info): New class.
	(capture_info::capture_info): New constructor.
	(capture_info::walk_match): New method.
	(capture_info::walk_result): New method.
	(capture_info::walk_c_expr): New method.
	(dt_simplify::gen): Handle preserving side-effects for
	GENERIC code generation.
	(decision_tree::gen_generic): Do not reject operands
	with TREE_SIDE_EFFECTS.
	* generic-match.h: New file.
	* generic-match-head.c: Include generic-match.h, not gimple-match.h.
	* match.pd: Add some constant folding patterns from fold-const.c.
	* fold-const.c: Include generic-match.h.
	(fold_unary_loc): Dispatch to generic_simplify.
	(fold_ternary_loc): Likewise.
	(fold_binary_loc): Likewise.  Remove patterns now implemented
	by generic_simplify.
	* gimple-fold.c (replace_stmt_with_simplification): New function.
	(fold_stmt_1): Add valueize parameter, dispatch to gimple_simplify.
	(no_follow_ssa_edges): New function.
	(fold_stmt): New overload with valueization hook.  Use
	no_follow_ssa_edges for the overload without hook.
	(fold_stmt_inplace): Likewise.
	* gimple-fold.h (no_follow_ssa_edges): Declare.
