--- Comment #1 from Drea Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.  The CRC pass is messing this up:
```

  if (0 != 0)
    goto <bb 7>; [12.50%]
  else
    goto <bb 10>; [87.50%]

  <bb 10> [local count: 939524096]:
  goto <bb 4>; [100.00%]

  <bb 7> [local count: 134217728]:
  crc_26 = .CRC_REV (crc_8, 0, 79764919);
```
