// An `extern LIB "csym"` reference must name something real, exactly like
|
|
// its `extern LIB` twin (example 1620): `nosuchunit` names neither a
|
|
// #library constant nor a named `#import c` unit, so this is a compile-time
|
|
// diagnostic — the bogus library reference is caught BEFORE the symbol
|
|
// would silently resolve through whatever image happens to carry it.
|
|
//
|
|
// Regression (FFI-linkage Part B): `checkExternRefs` validated only a
|
|
// `extern` (extern-import shape) library_ref and skipped the `extern` keyword's
|
|
// `extern_lib`, so a bogus `extern` lib reference compiled silently (the
|
|
// symbol resolved via the default image and ran). Prerequisite for
|
|
// migrating the fn-decl `extern` path onto `extern`.
