More precisely, I'd like to see which library a certain function comes from e.g. be able to find out that the definition of printf used in the analyzed program is in stdio.h. I thought using 'const char *getMangledName(const GlobalDecl &D)' from CodeGenModule.h could provide some information, however it seems that CodeGenModule is just used internally and, besides that, one should not count on the mangled names format.

Try getting a source location from the decl.  Given a source location, the SourceManager object can map the location back to a file/line/col for you.
