>Description:

gcj is not emitting some important symbol when generating switch
statement code.  This is a fairly new regression. With the test code
below, you'll see:

/tmp/ccGnYxUm.o(.text+0x24): undefined reference to `.L8'

>How-To-Repeat:

$ gcj SwitchTest.java -O1  --main=SwitchTest

public class SwitchTest
{
  public static void main (String args[])
    {
      String attTypeString = "";

      switch (args.length) {
      case 1:
          attTypeString = "string";
      case 4:
          attTypeString = "ID";;
      case 5:
          attTypeString = "IDREF";;
      case 6:
          attTypeString = "NMTOKEN";;
      case 7:
          attTypeString = "NOTATION";;
      default:
          ;
      }
    }
}
