...is to look at all the global variables: for (auto &G : M.globals()) for (auto &V : G.operands()) if (auto F = dyn_cast<Function>(V)) Of course, instructions can also refer to functions, both as direct calls and otherwise: for (auto &F : M) { for (auto &I : inst_range(F)) { for (auto &V : I.operands()) if (auto F = dyn_cast<Function>(V)) But there are other things as well, for example it seems there is something called a personality function that can be a pointer to another function, so need to add that if (F.hasPersonalityFn()) I...
