Close https://github.com/llvm/llvm-project/issues/77995 The cause of the issue is that straight forward that we recorded the '#pragma once' information in named modules, which is an overlook. I tried to not record the header's information completely within named modules. But the tests look not happy with some diagnosing problems, which needs to be looked in details.
