@tskeith Thank for you reviewing! I think that this covers all of your suggestions.



================
Comment at: flang/lib/Frontend/FrontendAction.cpp:40
+  if (input.file() != "-") {
+    if (!llvm::vfs::getRealFileSystem()->exists(input.file())) {
+      ci.diagnostics().Report(clang::diag::err_fe_error_reading)

* exists
* is not a directory

If any of these ^^^ is not true, a diagnostic is generated (different for each condition).
