Linker option to dump dependency graph

Sorry, I didn’t notice that you are asking not to me but to Fangrui. Please disregard my previous email.

I didn’t pay much attention when “replying all”. I did actually mean to ask you :).

It’s coming up repeatedly in Chrome that I want to be able to find the reason why a symbol is included, so even if there’s a patch I could pull in myself to answer these queries, that would be appreciated :).

You may use -y foo to trace a symbol. -t and -M are also useful.

I’m still very much interested in this feature. Wondering if an llvm bug was filed to track it? If not, would it be useful for me to file one?
