Take a StringRef instead of a "const char *". Take a "std::error_code &" instead of a "std::string &" for error. A create static method would be even better, but this patch is already a bit too big. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@216393 91177308-0d34-0410-b5e6-96231b3b80d8
