================
Comment at: clang/lib/Lex/Lexer.cpp:1050
 
-  // If the macro's spelling has no FileID, then it's actually a token paste
-  // or stringization (or similar) and not a macro at all.
-  if (!SM.getFileEntryForID(SM.getFileID(SM.getSpellingLoc(Loc))))
+  // If the macro's spelling isn't FileID or came from the scratch space, then
+  // it's actually a token paste or stringization (or similar) and not a macro
----------------
nit: isn't FileID or from scratch space
