Interesting, thanks for sharing. However, at quick look, it seems to require 
other CUDA libraries (`libcuda`, `libcublas`, etc.), which also aren't 
available for FreeBSD.

Herald added subscribers: cfe-commits, emaste.
Herald added a project: clang.

This allows `clang` to be used to compile CUDA programs. Compiled
simple helloworld.cu with this.

I'm seeing quite similar errors on FreeBSD with Clang 8 and 9:

Any idea how to fix this?
