--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
both_nonnegative looks to be fixed:

        movq    %rdi, %rax
        orq     %rsi, %rax
        notq    %rax
        shrq    $63, %rax
        ret

  _8 =3D a_4(D) | b_5(D);
  _9 =3D _8 >=3D 0;
  _6 =3D (int) _9;

different_sign also seems to be fixed:
        .cfi_startproc
        xorq    %rsi, %rdi
        shrq    $63, %rdi
        movq    %rdi, %rax
        ret
  _6 =3D a_2(D) ^ b_3(D);
  _1 =3D _6 < 0;=
