@flip1995 You may want to cherry-pick the top commit of branch bootstrap-is-multiple-of in the samueltardieu/rust repository (or curl https://github.com/samueltardieu/rust/commit/67c56ea97c3565ac0f9acdd98d078df2e6668251.patch | git am).

Or I can submit it separately but that would require time to be merged before this PR is rebased, as there is currently a significant backlog in the queue.
