System: Linux louie 2.4.7-10smp #1 SMP Thu Sep 6 17:09:31 EDT 2001 i686 unknown
Architecture: i686
host: i686-pc-linux-gnu

>Description:
Here's a bug in how gcj evaluates method arguments....
public class bug
{
private static int first (int x, int y)
{
return x;
}
public static void main (String[] args)
{
int l = args.length;
/* This should print:
0
0
1
*/
System.out.println (l);
System.out.println (first (l, ++l));
System.out.println (l);
}
}
This is correct output...
[green@build green]$ gcj -o bug --main=bug bug.java -O0
[green@build green]$ ./bug
0
0
1
This is bad output...
[green@build green]$ gcj -o bug --main=bug bug.java -O2
[green@build green]$ ./bug
0

Is looks as though the rtl we're generating is bad from the start - so
it's unlikely to be a problem with any on the rtl-based optimizations.
