It does not allow multiple outputs for `-ptx` and `-cubin` compilations, same as clang behaves now: ~/local/cuda-11.3/bin/nvcc -gencode=arch=compute_60,code=sm_60 -gencode=arch=compute_70,code=sm_70 -ptx foo.cu nvcc fatal : Option '--ptx (-ptx)' is not allowed when compiling for multiple GPU architectures NVCC does allow `-E` with multiple targets, but it does produce output for only *one* of them. NVCC does bundle outputs for multiple GPU variants if `-cubin` is used.
