How to get the assembly code of a CUDA kernel?

I have some kernels that I have written in both OpenCL and CUDA. When running OpenCL programs in the AMD profiler, it allows me to view the assembly code of the kernel. I would like to compare this with the assembly code of the CUDA kernels to compare compiler optimizations between the two languages. I have been playing around with the Nvidia Profiler, but am still at a loss on how to get the assembly code of my kernels. How does one go about doing this?
