| // Tests that the correct span is used to determine the edition of an attribute that was safe to use |
| // in earlier editions, but has become `unsafe` in later editions. |
| // |
| // Determining the correct edition is non-trivial because of macro expansion. For instance, |
| // the `thread_local!` macro (defined in std and hence using the most recent edition) parses the |
| // attribute, and then re-emits it. Therefore, the span of the `#` token starting the |
| // `#[no_mangle]` attribute has std's edition, while the attribute name has the edition of this |
| // file, which may be different. |
