Close https://github.com/llvm/llvm-project/issues/62707 As we discussed before, we'll forbid the use of implicit generated path for C++20 modules. And as I mentioned in https://github.com/llvm/llvm-project/issues/62707, we've emitted a warning for clang17 and we'll make it a hard error in clang18. And the patch addresses the decision.
