I noticed you're using cuda_runtime.h in the source file. Where are you getting this file? From the CUDA toolkit? Since the error is in the back-end, can you just post the .ll or .bc file you are trying to compile?

I am trying to generate PTX code for 'nbody' sample program's kernel (nbody_kernel.cu) using clang/LLVM version 3.2. The nbody CUDA program is available in Nvidia's SDK. I am referring to https://github.com/jholewinski/llvm-ptx-samples project. Following are my commands, clang++ -O4 -S -I/usr/local/cuda/include -emit-llvm -target nvptx64 nbody_kernel.cu -o nbody_kernel.ll
