--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> --- I've recently talked with Honza in the context of PGO with atomic counter updates and we've discussed around eventually optimizing some cases. But I'm sceptical we can identify safe cases given the optimization barrier they currently provide also prevents code motion across them.
