> Per the LLVM PR guidelines, please avoid force pushes on your branch: they make it harder to review, because you can no longer see what's changed since the previous version. If rebasing is necessary, you can use a merge commit from the base branch. When you squash and merge upon submission, the merge commit (and any fixup commits) will disappear.

You can use getcord/spr if you prefer rebases and force pushes. The tool will propagate changes from your local branch to the PR branch and the PR branch only performs merges. https://maskray.me/blog/2023-09-09-reflections-on-llvm-switch-to-github-pull-requests#my-workflow
