Put up a patch so `-gmodules` doesn't drop the `DW_AT_APPLE_runtime_class` from the forward declarations that it creates: https://github.com/llvm/llvm-project/pull/120154, which resolves this issue. It doesn't require any changes to LLDB (it seems like we don't need the `ObjCObjectOrInterfaceType` to have a definition in order to attach methods to it).
Though we might still need to do this eager definition fetching for users who can't recompile their objective-c codebases with newer compilers. Also, I'm not entirely sure this patch here is correct yet. I think the way it's currently written doesn't handle the case where we call `ParseStructureLikeDIE` with a forward declaration, and then later on with a definition DIE. For C++ structures we handle that by updating the UniqueTypeMap with the definition DIE, etc. We'll probably have to do what we do for enums and also put the definition DIE into the `DIEToType` map. https://github.com/llvm/llvm-project/pull/119860 _______________________________________________ lldb-commits mailing list lldb-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits
