Determine all global variables of a module

Question

How to determine all global variables of a LLVM module?

llvm::Module class has getGlobalList() method:

/// Get the Module's list of global variables.
GlobalListType         &getGlobalList()             { return GlobalList; }

So you can do something like:

for (auto &Global : M->getModule()->getGlobalList()) ...
