There's an issue in the translator today where, for a CallsiteLoc, if the callee does not have a DI scope (perhaps due to compile options or optimizations), it may get propagated the DI scope of its callsite's parent function, which will create a non-existent DILocation combining line & col number from one file, and the filename from another. The root problem is we cannot propagate the parent scope when translating the callee location, as it no longer applies to inlined locations (see code diff and hopefully this will make sense). To facilitate this, the importer is also changed so that callee scopes are fused with the callee FileLineCol loc, instead of on the Callsite loc itself. This comes with the benefit that we now have a symmetric Callsite loc representation. If we required the callee scope be always annotated on the Callsite loc, it would be hard for generic inlining passes to maintain that, since it would have to somehow understand the semantics of the fused metadata and pull it out while inlining. |
