Hi Nick,
Thanks for the reply and openness to make tools more compatible!
(even when llvm-nm made some coordination mistakes...)

-M seems more like a llvm-nm problem and I believe it is almost unused.
I think llvm-nm folks should think how to handle the -s conflict with
macOS. nm probably should not be bothered with this llvm-nm problem.
I think -M can be used for possibly more useful options in the future.

The latest version of llvm-nm has -V: https://llvm.org/docs/CommandGuide/llvm-nm.html
Having -V as an alias for --version seems a convention for quite a few
utilities.

Thanks! Having -U for --defined-only will be great.

Thanks for noticing this. I just filed one: https://sourceware.org/bugzilla/show_bug.cgi?id=29135 :)
Having -W/--no-weak will be great, too.
