There are  two kinds of sources of args in this discussion:

  - from lldb console through stdin which is not raw.
  - from LLDB_SERVER_LOG_FILE environment variables which are raw

We expect to call a GetFlattenedWindowsCommandString for raw input. However it seems not the case for now. 

What about adding a TODO in the following in ProcessWindowsLauncher. 

Would like a solution to proceed.

+bool GetFlattenedWindowsCommandString(Args args, std::string &command) {
+  if (args.empty())
+    return false;
+  std::vector<llvm::StringRef> args_ref;
+  for (auto &entry : args.entries())
+     args_ref.push_back(entry.ref);
+  // TODO: only flatten raw input.
+  // Inputs from lldb console through the stdin are not raw, for example,
+  // A command line like "dir c:\" is attained as "dir c":\\". Trying to flatten such
+  // input will result in unexpected errors. In this case, the flattend string will be
+  // interpreted as "dir c:\\ which is a wrong usage of `dir` command.
+  command = llvm::sys::flattenWindowsCommandLine(args_ref);
+  return true;
+} // namespace
