>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:
;
}
}
}
