Header files that come with CUDA are assuming split host/device compilation and are not usable by clang out of the box. With a bit of preprocessor magic it's possible to twist them into something clang can use. This wrapper always includes CUDA headers exactly the same way during host and device compilation passes and produces identical preprocessed content during host and device side compilation for sm_35 GPUs. Device compilation passes for older GPUs will see a smaller subset of device functions supported by particular GPU. The wrapper assumes specific contents of CUDA header files and works only with CUDA 7.0 and 7.5. Differential Revision: http://reviews.llvm.org/D13171 llvm-svn: 253388
