--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
phiopt match-simplify trying:
        b_15 >=3D 0 ? iftmp.1_16 : 1
Matching expression match.pd:2006, gimple-match-5.cc:23
Matching expression match.pd:2006, gimple-match-5.cc:23
Applying pattern match.pd:5311, gimple-match-1.cc:3381
Applying pattern match.pd:1393, gimple-match-2.cc:7726
Applying pattern match.pd:1901, gimple-match-4.cc:680
Applying pattern match.pd:4781, gimple-match-10.cc:16483
Folded into the sequence:
_11 =3D b_15 >=3D 0;
_20 =3D (int) _11;
_19 =3D b_15 < 0;
_26 =3D (int) _19;
_18 =3D iftmp.1_16 | _26;
statement un-sinked:
iftmp.1_16 =3D b_15 >> 6;


Before:
  # RANGE [irange] int [0, 1]
  iftmp.1_16 =3D b_15 >> 6;

Dup of bug 110252.
