Why does cuobjdump -sass show NOPs at the end of a cubin file?

I’m curious why cuobjdump -sass my.cubin shows a bunch of NOPs at the end of the code.

This matches the documentation for the example of cuobjdump: CUDA Binary Utilities :: CUDA Toolkit Documentation

However disassembling with nvdisasm my.cubin appears to end exactly at the final break instruction.

.L_1:
        /*0100*/                   BRA `(.L_1);
.L_28:

For reference I’m trying this all using the simple “vectorAdd” sample included with the CUDA examples.

Hi dear customer ,
Could you please file us a ticket following the instruction here Getting Help with CUDA NVCC Compiler - #3 we will take a further look .Thanks .
