[PATCH] D115604: [Support] Expand `<CFGDIR>` as the base directory in configuration files.

[Serge Pavlov via Phabricator via cfe-commits]

sepavloff added inline comments.


================
Comment at: llvm/lib/Support/CommandLine.cpp:1099
+    else
+      llvm::sys::path::append(ResponseFile, LHS);
+    ResponseFile.append(BasePath);
----------------
What happens if `<CFGDIR>` is used without trailing path? Such line:
```
    --sysroot=<CFGDIR> -abc
```
 would be processed correctly?
