There weren't any merge conflicts, were there? If you amend and force-push to have only 1 commit on the pull request, then you shouldn't do that. See https://llvm.org/docs/GitHub.html#updating-pull-requests.

Even if there are merge conflicts, you should rebase your existing commits instead of resetting your branch and creating a single new commit.
