Comment at: clang/test/Driver/cuda-version-check.cu:13
 // RUN:    FileCheck %s --check-prefix=UNKNOWN_VERSION
+// CUDA-11.1 does not carry version.txt file. Make sure we still detect it as a
+// new version and handle it the same as we handle other new CUDA versions.

This assertion appears to be incorrect. I've just installed 11.0 update1 using Ubuntu [[ https://developer.download.nvidia.com/compute/cuda/11.0.3/local_installers/cuda_11.0.3_450.51.06_linux.run | .run ]] installer I've got from https://developer.nvidia.com/cuda-11.0-update1-download-archive  and the installed version does have version.txt saying 

```
CUDA Version 11.0.228
```

Did you use some other installer variant?
