// Check that we detect imports (of built-in attributes) that are redundant due to
// the language prelude and that we emit a reasonable diagnostic.
//~^^ NOTE the item `allow` is already defined by the extern prelude
// Note that we use the term "extern prelude" in the label even though "language prelude"
// would be more correct. However, it's not worth special-casing this.
// See also the discussion in <https://github.com/rust-lang/rust/pull/122954>.
