[PATCH] D38790: [ELF] Avoid keeping useless undefined symbols in .dynsym.

[Igor Kudrin via Phabricator via llvm-commits]

ikudrin created this revision.
ikudrin added a project: lld.
Herald added a subscriber: emaste.

These symbols introduce unwanted dependencies.
It may result in creating a DSO which prevents linking an executable which uses that DSO,
for example, if another linker is used to link that executable, or if lld starts reporting
unresolved symbols in shared libraries one day.
