+	PR middle-end/85811
+	* fold-const.c (tree_expr_finite_p): New function to test whether

+	(tree_expr_infinite_p):  New function to test whether a tree
+	expression must be infinite, i.e. a FP infinity.
+	(tree_expr_maybe_infinite_p): New function to test whether a tree
+	expression may be infinite, i.e. a FP infinity.
+	(tree_expr_signaling_nan_p): New function to test whether a tree
+	expression must evaluate to a signaling NaN (sNaN).
+	(tree_expr_maybe_signaling_nan_p): New function to test whether a
+	tree expression may be a signaling NaN (sNaN).
+	(tree_expr_nan_p): New function to test whether a tree expression

+	(tree_expr_maybe_nan_p): New function to test whether a tree
+	expression me be a (quiet or signaling) NaN.
+	(tree_binary_nonnegative_warnv_p) [MAX_EXPR]: In the presence

+	In the presence of signaling NaNs, fmax is only guaranteed to be
