Yes, I was thinking that it can be used for printing DSO dumps for example when you know their load addresses. My real intention was a bit different though. Recently I compared differences between GNU objdump and llvm-objdump,
and found we do not support this option though it looked potentially useful to me. So I tried to improve compatibility with the GNU objdump command line.

Oh, right. I updated the description.
