--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Applying pattern match.pd:4705, gimple-match-10.cc:15878
gimple_simplified to _38 =3D (<signed-boolean:32>) _16;
_66 =3D -_38;
Global Exported: _66 =3D [irange] <signed-boolean:32> [-1, 0]
Folded into: _66 =3D -_38;


    /* a ? -1 : 0 -> -a.  No need to check the TYPE_PRECISION not being 1
       here as the powerof2cst case above will handle that case correctly. =
 */
    (if (INTEGRAL_TYPE_P (type) && integer_all_onesp (@1))
     (negate (convert (convert:boolean_type_node @0))))))


I guess is mine ....=
