It is not necessary, because now configuration file is expanded with the flag `RelativeNames` set. It however seems more correct to check for `InConfigFile` also, hopefully it make code a bit clearly.


================
Comment at: llvm/lib/Support/CommandLine.cpp:1204
+    StringRef FileName;
+    if (ArgStr[0] == '@') {
+      FileName = ArgStr.drop_front(1);

You are right. Initially this patch was combined with D136354, where additional checks was added. I changed this code to be more natural.


================
Comment at: llvm/lib/Support/CommandLine.cpp:1205
+    if (ArgStr[0] == '@') {
+      FileName = ArgStr.drop_front(1);
+      if (!llvm::sys::path::is_relative(FileName))

Yes, changed code accordingly.
