Re: Cabal not updated after rebase?
Thank you so much Richard - it worked! And you are right, I had a `git add -u` at some point. This is what happens when I don’t review my changes closely! I had no idea I made changes to libraries/Cabal and such. Anyways, the diff is on Phab again, D5229. Hope to see feedback :) My From: Richard Eisenberg Sent: Monday, December 3, 2018 9:35 PM To: My Nguyen Cc: Krzysztof Gogolewski; ghc-devs@haskell.org Subject: Re: Cabal not updated after rebase? Detached HEADs are normal with submodules. (I suppose sentences like that would have gotten me executed several centuries ago...)

I imagine you didn't mean to do this. (This has happened to me with an ill-timed `git add -u` while rebasing. Perhaps that's what caused the trouble for you, too.) To fix, you can manually `git checkout abcdefabcdef` each erroneously changed submodule to point to the right commit from HEAD. Then, `git add` each submodule in the ghc repo (i.e. not inside any submodule) and try again. I hope this helps!
