+CUDA Support in Clang
+---------------------
+Clang has experimental support for end-to-end CUDA compilation now:
+
+- The driver now detects CUDA installation, creates host and device compilation
+  pipelines, links device-side code with appropriate CUDA bitcode and produces
+  single object file with host and GPU code.
+
+- Implemented target attribute-based function overloading which allows clang to
+  compile CUDA sources without splitting them into separate host/device TUs.
