git llvm revert rL365889 didn't work, so just doing it by hand.
What about it didn't work? Should it have been git llvm revert r365889? If that doesn't work, have you tried the other options described at https://llvm.org/docs/GettingStarted.html#reverting-a-change-when-using-git?
Yes I tried those. It says
`git log --format=%H --grep '^llvm-svn: 365889$' 'HEAD~10000...HEAD'` returned 128 fatal: ambiguous argument 'HEAD~10000...HEAD': unknown revision or path not in the working tree. Use '--' to separate paths from revisions, like this: 'git <command> [<revision>...] -- [<file>...]'
I think because I deleted that branch already so it isn't local? I'm not really sure, truthfully.
I don't think it's anything to do with your local branch. You should be on an up-to-date master to run it, I think. If that doesn't work, post on the mailing list about it, because it should. Don't just do it by hand.
Yes, git llvm revert is ultimately a wrapper around git revert <git commit that git llvm finds>, so if you don't have the commit in your history (with --depth 1 you won't have anything), it won't work.
Certainly we could make it print a better error message, and also handle other call signs (rLNNNNNN, rCNNNNNN, rLLDNNNNNN, etc.)
