[Michał Górny via Phabricator via cfe-commits]

mgorny added inline comments.


================
Comment at: llvm/include/llvm/Support/CommandLine.h:2138
+  /// directories specified by SearchDirs field.
+  bool findConfigFile(StringRef FileName, std::string &FilePath);
+
----------------
I'm sorry if I'm missing something obvious but is there a specific reason you're using `std::string` here when pretty much all prior call sites were using `SmallString`?
