* Use StringRef instead of std::string& * Return a std::unique_ptr<Module> instead of taking an optional module to write to (was not really used). * Use current comment style. * Use current naming convention. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@215989 91177308-0d34-0410-b5e6-96231b3b80d8
