Thanks a lot! Is there a way to notice when a compiler upgrade causes a lot of similar reports to be generated? If so, would it be possible to send the reports that would be generated to only me and llvm@lists.linux.dev? We want to get notified when there would be a lot of reports generated after a compiler upgrade (because that usually points to a compiler regression) but kernel developers shouldn't get notified (since there is not anything for them to do). > > The current revision is broken and unrelated changes are getting > > notified.

You should be able to move to the latest whenever now, the regression I noticed was fixed with a revert (it has since been reapplied with a fix). Cheers, Nathan
