I've never been able to figure this one out:
llvm/lib/VMCore/PassManager.cpp:938: virtual void
Assertion `0 && "Unable to handle Pass that requires lower level Analysis
In the past, I've resolved this by disabling random addRequired calls in the
offending Pass, even when those dependencies are real.
So what does this assert mean, exactly? How do I find out just what is wrong
with the Pass dependencies?
