| # Once a day, attempt to roll the pinned nightly and stable toolchain versions | |
| # and update the codebase as necessary (in particular, by regenerating the files | |
| # which store expected compiler output for UI tests; this output is not stable | |
| # and may change between compiler versions). On success, submit the changes as a | |
| # new PR. Note that this does not guarantee that the roll will succeed: PRs go | |
| # through many tests which are not exercised here, and so the generated PR may | |
| # still fail CI. In particular, some nightly releases do not support all of the | |
| # target architectures that we use in CI; attempting to roll to any such release | |
| # will fail. | |
