--message 'Dear @*T-miri*, | |
It would appear that the [Miri cron job build]('"https://github.com/$GITHUB_REPOSITORY/actions/runs/$GITHUB_RUN_ID"') failed. | |
This likely means that rustc changed the miri directory and | |
we now need to do a [`./miri rustc-pull`](https://github.com/rust-lang/miri/blob/master/CONTRIBUTING.md#importing-changes-from-the-rustc-repo). | |
Would you mind investigating this issue? | |
Thanks in advance! | |
Sincerely, | |
