[PATCH] D96837: Add !retain metadata to represent SHF_GNU_RETAIN on ELF platforms

[Petr Hosek via Phabricator via llvm-commits]

phosek added a comment.

Have you considered using `llvm.used` instead of introducing new metadata type? `__attribute__((used))` is lowered to `llvm.used` so this should be equivalent.
