What's the best way of debugging constant folding warnings?

[astanziola]

I have a large program working with large arrays that shows some constant folding warnings. However, except for the name of the specific instruction being constant folded, which is not really informative, I have no idea where this issue is happening.

What is the best way of debugging such warning? Is there a way to make the program stop at the warning as if it was an error?
