#  Makefile: Cuda clang demo Makefile for both amdgcn and nvptx targets.
#            amdgcn GPU targets begin with "gfx". nvptx targets begin
#            with sm_.  Example: To build and run on k4000 do this:
#
#            export LLVM_GPU_ARCH=sm_30
#            make run
#
#  Run "make help" to see other options for this Makefile
