[LLVMdev] Probable error in InstCombine
...optimization level.
This appears to be the relevant code:
InstCombineAddSub.cpp:1556

> match(Op0, m_Zero()))
> return BinaryOperator::CreateSDiv(X, ConstantExpr::getNeg(C));

[LLVMdev] Handling of undef in the IR
Hi all,
I have a very simple test case (thanks to bugpoint) that hit an assert in reassociate.

The function is taking a Constant as argument, but the assert does not expect an undef. I’m 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
