Portable SIMD is developed in its own repository. If possible, consider making this change to rust-lang/portable-simd instead.

⚠️ Warning ⚠️

  • There are issue links (such as #123) in the commit messages of the following commits.
    Please move them to the PR description, to avoid spamming the issues with references to the commit, and so this bot can automatically canonicalize them to avoid issues with subtree.

  • The following commits have merge commits (commits with multiple parents) in your changes. We have a no merge policy so these commits will need to be removed for this pull request to be merged.

    You can start a rebase with the following commands:

    $ # rebase
$ git pull --rebase https://github.com/rust-lang/rust.git main
$ git push --force-with-lease

In the future putting "subtree update" in the same keeps rustbot quiet

I'd really like portable_simd to switch to a josh subtree, so we can get rid of the (kind of fragile) bash script. Presumably its sync tool handles the labels etc.
