So, this triple is only used for locating the CUDA library itself. In that case it's generally assumed that it will match whatever file structure the host computer is using. Specifically, right now all it's used for is `HostTriple.isOSWindows()`. > In this situation the LLVM_HOST_TRIPLE would not be the right triple at all. > Does OpenMP currently handle the cross-compilation scenario above? I don't think anyone's tried OpenMP with cross compilation. Most likely because it's only supported on Linux currently. I actually don't know what would happen if you tried.
