Correct. cuda_runtime.h (and all it pulls in) is -include'd under the hood by nvcc.

I'll add a test to verify that "-include cuda_runtime.h" shows up on cc1 command line where/when it's expected.
What would be a good way to test the wrapper itself within clang tree without real CUDA headers?
I've done fair amount of manual testing outside of clang source tree.
- manual comparison of preprocessed output from cuda_runtime.h between host and device passes.
- compiled 39 out of 46 thrust examples and verified that they produce output identical to nvcc-compiled binaries.
