[PATCH] D135737: [LLD][ELF] restore behaviour of __real_foo being a weak reference to a lazy foo

[ben via Phabricator via llvm-commits]

bd1976llvm updated this revision to Diff 467171.
bd1976llvm added a comment.

Improve testing and add tests to show that symbol `foo` is considered referenced by LLD even if all references are redirected by `--wrap foo`. This property means that a `__wrap_foo` function that contains calls to `__real_foo` will not be called if `foo` is not included in the link.
