The attrubite is applicable to functions and variables and changes the linkage of the subject to internal. This is the same functionality as C-style "static", but applicable to class methods; and the same as anonymouns namespaces, but can apply to individual methods of a class. Following the proposal in http://lists.llvm.org/pipermail/cfe-dev/2015-October/045580.html llvm-svn: 252648
