bors 984a6bf9c1 Auto merge of #92175 - Aaron1011:fix-missing-source-file, r=cjgillot ... Import `SourceFile`s from crate before decoding foreign `Span` Fixes #92163 Fixes #92014 When writing to the incremental cache, we encode all `Span`s we encounter, regardless of whether or not their `SourceFile` comes from the local crate, or from a foreign crate. When we decode a `Span`, we use the `StableSourceFileId` we encoded to locate the matching `SourceFile` in the current session. If this id corresponds to a `SourceFile` from another crate, then we need to have already imported that `SourceFile` into our current session. This usually happens automatically during resolution / macro expansion, when we try to resolve definitions from other crates. In certain cases, however, we may try to load a `Span` from a transitive dependency without having ever imported the `SourceFile`s from that crate, leading to an ICE. This PR fixes the issue by enconding the `SourceFile`'s `CrateNum` when we encode a `Span`. During decoding, we call `imported_source_files()` when we encounter a foreign `CrateNum`, which ensure that all `SourceFile`s from that crate are imported into the current session.		2021-12-31 16:38:23 +00:00
