> This came up in the fuzz test added by [~vlsi]. In RexCall#isAlwaysTrue, the return value for IS FALSE is the result of checking isAlwaysTrue for the operand. Similarly, the behaviour seems to also be correct for IS NOT FALSE and IS NOT TRUE. Could someone take a quick look and tell me if I'm missing something?
