balazske added inline comments.

================
Comment at: clang/lib/CrossTU/CrossTranslationUnit.cpp:362
 
-  return ASTUnit::LoadFromASTFile(
-      std::string(ASTFilePath), CI.getPCHContainerOperations()->getRawReader(),
-      ASTUnit::LoadEverything, Diags, CI.getFileSystemOpts());
+  auto LoadFromFile = [this](StringRef Path) {
+    IntrusiveRefCntPtr<DiagnosticOptions> DiagOpts = new DiagnosticOptions();
----------------
Is here a lambda necessary? I think it must not be over-used. In this case we 
can construct the file path as the first step and then use it to load the file, 
without using lambda call.


================
Comment at: clang/lib/CrossTU/CrossTranslationUnit.cpp:583
+                 CommandLineArgs.begin(),
+                 [](auto &&CmdPart) { return CmdPart.c_str(); });
+
----------------
Is here a special reason to use `auto &&` type (and not `auto &` or 
`std::string &`)? Probably this code is faulty: The `CmdPart` is moved out and 
then destructed, before the content of it (where the `c_str` points to) is used?
