            Bug ID: 35648
           Summary: Test failure with CUDA 9.0
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: CUDA

                CC: llvm-bugs at lists.llvm.org

The Driver/unknown-std.cpp test is failing with CUDA 9.0 due to an unsupported
architecture "sm_20" which was dropped in CUDA 9.0. I got this on revision
320484:
