A good small example:
public class t
{
static final int nn()
{
return 0;
}
public static void main (String[] argv)
{
int n = 0;
for (int i = 0; i < 1000; i++)
n += nn();
System.out.println(n);
}
}

Actually the way this used to work before the tree-ssa was during inlining we called out to the front-
end to merge the two variables.

Ada and Java bugs are not release-critical; therefore, I've removed the target
milsetone.

Actually this still does not work:
>From .final_cleanup:
<L1>:;
_Jv_InitClass (&t.class);
;
i = i + 1;
if (i == 1000) goto <L4>; else goto <L1>;

I should copy and paste the full tree dump:
<bb 0>:
_Jv_InitClass (&t.class);
n = 0;
<L1>:;
_Jv_InitClass (&t.class);
n = n + 1;
;
if (n == 1000) goto <L4>; else goto <L1>;
The call to _Jv_InitClass is in the inner loop which causes a slow down and use not to be able to remove
the loop.
