// This is just like unreachable_pub.rs, but without the
// `crate_visibility_modifier` feature (so that we can test the suggestions to
// use `pub(crate)` that are given when that feature is off, as opposed to the
// suggestions to use `crate` given when it is on). When that feature becomes
// stable, this test can be deleted.
// build-pass (FIXME(62277): could be check-pass?)

You can’t perform that action at this time.
