--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
What is interesting is if we look at the IR:

  _41 = .LOOP_DIST_ALIAS (3, _40);
  if (_41 != 0)
    goto <bb 3>; [90.00%]
  else
    goto <bb 4>; [10.00%]

  <bb 3> [local count: 430033601]:
  _29 = *_4;
  _30 = (char) _29;
  _31 = _7 & _30;
  goto <bb 5>; [100.00%]

  <bb 4> [local count: 47781512]:
  _47 = *_4;
  _48 = (char) _47;
  _49 = _7 & _48;

  <bb 5> [local count: 118111600]:
  # _46 = PHI <_49(4), _31(3)>

That code is the same on both edges even though not noticed being the same.
