// 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.
