Hi George,> When I compile llvm in release mode, the problem goes away! I don't understand?probably the function defined in the header is inlined into every function that calls it when optimization is turned on, but not when optimization is turned off. Ciao, Duncan.
Yes, the function is an inline function in PostDominators.h. In fact almost
all the functions in the header are inlined.

}
I wonder how to go about making sure it is visible in debug mode.

There are already a couple of other functions that have been put here to not be eliminated. BTW, is there no better way to mark a function as used externally? Tobi
All the functions in LinkAllPasses.h are passes. I am not sure whether it takes inline functions. I added createPostDomTree() to LinkAllPasses.h but I get the same error. I wonder whether it was even worth it making the functions inline for PostDominators.h.
