It's given to a kernel rather than for a loop though. So I think this `simd` pragma is useful. My only worry is that other OpenMP features might not work well in OpenCL and we have no way to reject them at the moment.


We have special flag '-fopenmp-simd' to support only simd-based constructs. We can allow to use only this subset of OpenMP in OpenCL programs and disable support for '-fopenmp'.
