Unfortunately, it breaks exception handling for Java
on at least i686-pc-linux-gnu. Simple testcase:
public class Hello
 {
 public static void main (String[] args) throws Exception
 {
 throw new Exception ("Snafu!");
 }
 }
This now unceremoniously aborts with an "Aborted" message
instead of the expected stack trace. I reverted your patch and
things started behaving as expected.
It also causes quite a few libjava testsuite failures (again,
on i686-pc-linux-gnu).

IMHO, you should have also posted it to java-patches@gcc.gnu.org.
