// 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.

pub struct Outer;
impl Outer {
pub fn use_it() {
// This returns `first_crate::Foo`, causing
// us to encode the `AdtDef `first_crate::Foo` (along with its `Span`s)
// into the query cache for the `TypeckResults` for this function.
second_crate::make_it();
