Hi all,

I have a very simple test case (thanks to bugpoint) that hit an assert in reassociate.
(the assert is (C->getType()->isIntOrIntVectorTy() && "Cannot NEG a nonintegral value!"), function getNeg)

The function is taking a Constant as argument, but the assert does not expect an undef. Iâm not sure whose responsibility is it to handle that (caller?). 
Do we have to defensively assume that any Constant can be an undef anywhere and I should just add a check here?

Thanks,

Mehdi
