================
Comment at: llvm/tools/gold/gold-plugin.cpp:835
+  auto AddBuffer = [&](size_t Task, std::unique_ptr<MemoryBuffer> MB) {
+    Filenames[Task] = MB->getBufferIdentifier();
+  };
----------------
I may comment what's going-on here though, there is an implicit expectation that the API is always backed up by a file.
