Not really. Clang does not have a way to annotate device vs. kernel functions in C/C++ mode. You're probably better off trying to use OpenCL or CUDA mode in clang. In the clang unit tests, there is a cuda.h header that provides very basic support for these keywords: tests/SemaCUDA/cuda.h If you compile as CUDA (use .cu extension, or "-x cuda") and use this header, you will have

Thanks a lot Justin, I will remove the toolkit header. Just one last question..(maybe ;) ) If I do away with toolkit headers it says unknown type name '__device__'. Does this function qualifier have an alternative ? or I can just do away with ? -- View this message in context: http://llvm.1065342.n5.nabble.com/UNREACHABLE-executed-error-while-trying-to-generate-PTX-tp56026p56093.html
