>Description:

Here's a recent gcj regression....

louie[1180] gcj -o linkbug --main=linkbug linkbug.java -O2
/tmp/cccsuuSt.o: In function `linkbug::main(JArray<java::lang::String*>*)':
/tmp/cccsuuSt.o(.text+0x36): undefined reference to `.L10'
collect2: ld returned 1 exit status

>How-To-Repeat:

Try to compile and link the following with optimization turned on.

import gnu.java.rmi.server.*;

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

    switch (args.length) {
    case ProtocolConstants.STREAM_PROTOCOL:
      attTypeString = "string";
    case ProtocolConstants.SINGLE_OP_PROTOCOL:
      attTypeString = "ENTITY";
    case ProtocolConstants.MULTIPLEX_PROTOCOL:
      attTypeString = "ENUMERATION";
    case ProtocolConstants.PROTOCOL_ACK:
      attTypeString = "ID";
    case ProtocolConstants.PROTOCOL_NACK:
      attTypeString = "IDREF";
    case ProtocolConstants.MESSAGE_CALL:
      attTypeString = "NMTOKEN";
    case ProtocolConstants.MESSAGE_CALL_ACK:
      attTypeString = "NOTATION";
    default:
      ;
    }

    System.out.println (attTypeString);

    return;
  }
}
