We have: long int x; int _3; _Bool _5; _3 = 0 / 0; _5 = _3 == 822920; x_7 = _5 ? 822920 : 0; If I disable the added checks on dealing with rtx_equal_p, the ICE goes away. The problem is the mode for the result does not match the mode for the comparison (DImode for the result of the conditional and SImode for the comparison).
