I think if you define the pass ID in your host and use AddRequiredID instead of AddRequired: char LoadablePassID = 0; ... AU.addRequiredID(lookupPassInfo((intptr_t) &LoadablePassID)); then it should work if the loadable module references the same pass ID as an extern: extern char ExternalPassID; class ThePass : public ImmutablePass { public: ThePass : ImmutablePass(&ExternalPassID) {} }; An analysis group may...

Is it possible to AddRequired<...> a pass that is dynamically loaded? This would be very convenient for a course project but the documentation about pass interactions says nothing about dynamically loaded passes and vice versa. More specifically, to refer to the pass name in AddRequired, I need to declare it first but then I can't think of a way to load the module

...determine order of construction. I still don't understand how constructing members of an analysis group before the analysis group is constructed can work at all. Oh, I guess this clase in RegisterAGBase's constructor takes care of it: InterfaceInfo = const_cast<PassInfo*>(Pass::lookupPassInfo(InterfaceID)); if (InterfaceInfo == 0) { // First reference to Interface, register it now. registerPass(); InterfaceInfo = &PIObj; } Is that right? This PassManager stuff is extremely confusing and not well documented. Does it really buy us all that much? I can't believ...

I have downloaded and built LLVM 2.6 on MinGW but the sources do not seem to include anything
