Broken by this patch:
2005-02-06 Zdenek Dvorak <[EMAIL PROTECTED]>
* tree-ssa-loop-ivopts.c (rewrite_use_nonlinear_expr): Do not add
unnecessary cast to original induction variable increments.

I think this is an ivopt bug:
if (i_3 != 4294967295) goto ; else goto ;
i_3 is signed but the expression (I think), 4294967295, is unsigned, maybe we
are missing a
fold_convert.

Reduced testcase:
void abort (void);
int g(void)
{
return 1;
}
int main (void)
{
int i;
for (i = 4; i--;)
if (g () == 0)
break;
if (i >= 0)
abort ();
return 0;
}
