[steven at gcc dot gnu dot org]

------- Comment #15 from steven at gcc dot gnu dot org  2010-07-13 10:29 -------
Still not fixed with r162134:

;; Function bar (bar)

bar ()
{
  int prephitmp.4;

<bb 2>:
  prephitmp.4_1 = i;
  switch (prephitmp.4_1) <default: <L2>, case 0: <L0>>

<L0>:
  foo ();
  prephitmp.4_7 = i;

  # prephitmp.4_8 = PHI <prephitmp.4_1(2), prephitmp.4_7(3)>
<L2>:
  switch (prephitmp.4_8) <default: <L6>, case 0: <L4>>

<L4>:
  foo (); [tail call]

<L6>:
  return;

}
