builtins.c (fold_builtin_fputs): Don't bother converting the return type to integer_type_node... · 9675412f


	* builtins.c (fold_builtin_fputs): Don't bother converting the

	remainder, negation and absolute value may potentially trap.

	non-side-effecting tree nodes from an expression whose result
	is ignored.
	(fold_convert): Call fold_ignored_result when casting a value
