// Regression test for issue #92163
|
|
// Under certain circumstances, we may end up trying to
|
|
// decode a foreign `Span` from the incremental cache, without previously
|
|
// having imported the `SourceFile`s from the owning crate. This can happen
|
|
// if the `Span` comes from a transitive dependency (so we never try to resolve
|
|
// items from the crate during expansion/resolution).
|
|
//
|
|
// Previously, this would result in an ICE, since we would not have loaded
|
|
// the corresponding `SourceFile` for the `StableSourceFileId` we decoded.
|
|
// This test verifies that the decoding of a foreign `Span` will always
|
|
// try to import the `SourceFile`s from the foreign crate, instead of
|
|
// relying on that having already happened during expansion.
