+	* math/gen-libm-test.pl (adjust_arg): Remove function.
+	(special_function): Remove argument $in_func.  Only handle
+	generating output for tables of tests, not inside functions.
+	(parse_args): Likewise.
+	(generate_testfile): Remove variable $in_func.  Update call to
+	parse_args.
+	* math/libm-test.inc (PLUS_ZERO_INIT): Rename macro to plus_zero.
