--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I don't see this on the trunk:
_1 = (long unsigned int) i_31;
_2 = _1 * 4;
_3 = c_11(D) + _2;
v_12 = *_3;
_6 = a_15(D) + _2;
iftmp.1_8 = v_12 == 20 ? y_13(D) : x_14(D);
_26 = v_12 != 20 ? y_13(D) : x_14(D);
*_6 = _26;
_5 = b_17(D) + _2;
*_5 = iftmp.1_8;
i_19 = i_31 + 1;
ivtmp_28 = ivtmp_23 - 1;

That's fixed since we run VN over the if-converted body which is GCC 9.
