And LLVM policy agrees with you. Reverts should be reasonably timely. A change submitted two hours ago can be reverted without prior discussion. A change submitted two years ago should not be. Where exactly the transition point is is hard to say, but it’s probably in the handful of days in tree territory. If you are unsure, we encourage you to reply to the commit thread, give the author a bit to respond, and then proceed with the revert if the author doesn’t seem to be actively responding. https://llvm.org/docs/DeveloperPolicy.html Repository: rG LLVM Github Monorepo CHANGES SINCE LAST ACTION https://reviews.llvm.org/D96223/new/ https://reviews.llvm.org/D96223 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
