--- Comment #9 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Note this was exposed by r14-3350-g47b833a9abe19d which changed the origina=
l IR
From:
  _4 =3D VEC_COND_EXPR <_3, { -1 }, { 0 }>;
  _5 =3D VIEW_CONVERT_EXPR<vector(1) __int128 unsignedD.14>(_4);
  _6 =3D _5 =3D=3D { 0 };
  _7 =3D VEC_COND_EXPR <_6, { -1 }, { 0 }>;
  _8 =3D VIEW_CONVERT_EXPR<VD.4391>(_7);

To:
  _4 =3D ~_3;
  _5 =3D VEC_COND_EXPR <_4, { 0xffffffffffffffffffffffffffffffff }, { 0 }>;

Which is 100% correct and nothing wrong with that change there either.=
