[PATCH] D139816: [LTO] Don't generate invalid modules if "LTOPostLink" MD already exists

[Steven Wu via Phabricator via llvm-commits]

steven_wu added a comment.

My understanding of the flag is preventing you from:

- run the devirtual pass
- add some new function
- run the devirtual pass again

The LTO devirtualization passes require visibility for all the functions when the passes are run.
