/* { dg-do compile } */
/* { dg-options "-O1 -fdump-tree-dom3" } */
int
foo2 (distance, i, j)
     int distance;
     int i, j;
{
 int t = distance;
 if (t <= 0)
   t = ((t) >= 0 ? (t)  : -(t));
 return t;
}

/* There should be no ABS_EXPR.  */
/* { dg-final { scan-tree-dump-times "ABS_EXPR " 0 "dom3"} } */

Noticed while looking to why a test fail (gcc.dg/tree-ssa/20030807-6.c) on the lno branch 
after applying my patch to find ABS in phiopt.
