Close https://github.com/llvm/llvm-project/issues/61321 There are two linkage modes in clang now: one for internal linkage and one for formal linkage. The internal linkage is for the implementation details and the formal linkage is for the consistency with the C++ standard. Since we previously implemented the strong ownership for modules, the module linkage is not meaningful for linkers any more. So the module linkage should only be used for formal linkage.
