| // Issue #111888: this proc-macro crate imports another crate that itself |
| // exports a no_mangle function. |
| // |
| // That combination was broken for a period of time, because: |
| // |
| // In PR #99944 we *stopped* exporting no_mangle symbols from |
| // proc-macro crates. The constructed linker version script still referred |
| // to them, but resolving that discrepancy was left as a FIXME in the code. |
| // |
| // In PR #108017 we started telling the linker to check (via the |
| // `--no-undefined-version` linker invocation flag) that every symbol referenced |
| // in the "linker version script" is actually present in the linker input. So |
| // the unresolved discrepancy from #99944 started surfacing as a compile-time |
| // error. |
