Does 'code=sm_X' embed only binary (cubin) code, or also PTX code, or both?

I am little bit confused about the 'code=sm_X' option within the '-gencode' statement. An example: What does the NVCC compiler option -gencode arch=compute_13,code=sm_13 embed in the library ? Only the machine code (cubin code) for GPUs with CC…
