[Bug middle-end/28685] Multiple comparisons are not simplified

[rguenth at gcc dot gnu dot org]

------- Comment #2 from rguenth at gcc dot gnu dot org  2008-04-30 15:12 -------
A third variant is optimized by the ifcombine pass:

int test__(int a, int b)
{
  if (a < b)
    return 1;
  if (a == b)
    return 1;
  return 0;
}

in principle ifcombine could handle flow-less combining as well.  I'll put
that on my TODO.
