           Product: clang
           Version: trunk
          Hardware: All

Hi,

we are adding clang CUDA compatibility to more and more of our open source
projects (and it works like a charm!).

One thing that would help making the setup easier, especially on clusters with
module environments of various CUDA toolkits, would be if we can control
--cuda-path also via an environment variable. Should we maybe add that
functionality, e.g., reacting on an exported CUDA_ROOT or LLVM_CUDA_PATH ... or
similar?
