Any particular compiler generated static variables you have in mind? There aren't any C++ ones that come to mind - though of course LLVM isn't just for Clang/C++, but would be nice to have some documented use case, if there is one, for this. If there isn't one we can document/mention, it's probably still OK to do though, it's simple enough/cheap enough that it's not a big deal.
