--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Same problem as PR 110252 so dup.

phiopt match-simplify trying:
        _2 !=3D _5 ? 1 : _15
Matching expression match.pd:1991, gimple-match-5.cc:23
Matching expression match.pd:1991, gimple-match-5.cc:23
Matching expression match.pd:2480, gimple-match-4.cc:35
Matching expression match.pd:2483, gimple-match-3.cc:66
Applying pattern match.pd:4763, gimple-match-7.cc:16232
Folded into the sequence:
_14 =3D _2 !=3D _5;
_8 =3D (int) _14;
_7 =3D _8 | _15;
statement un-sinked:
_15 =3D _2;
Removing basic block 3
;; basic block 3, loop depth 0
;;  pred:       2
;;  succ:       4


  # RANGE [irange] int [0, 1] MASK 0x1 VALUE 0x0
  _15 =3D _2;
