TODO: fill in this section

+

Several of the LLVM libraries define static cl::opt instances that + will automatically be included in any program that links with that library. + This is a feature. However, sometimes it is necessary to know the value of the + command line option outside of the library. In these cases the library does or + should provide an external storage location that is accessible to users of the + library. Examples of this include the llvm::DebugFlag exported by the + lib/Support/Debug.cpp file and the llvm::TimePassesIsEnabled + flag exported by the lib/VMCore/Pass.cpp file.
