It's been a while since I looked at this, but as I recall, a fundamental assumption of MultiObDiskHashTable is that if we have a lookup result for a key K in the current file, that result supersedes any results from dependency files. So lookup won't look in those files if we have a local result (they are overridden) and merging doesn't take results from those files either. So I think the problem probably is that when we form a local result, we need to (but presumably don't) add all the imported results with the same key to the local result. https://github.com/llvm/llvm-project/pull/83237 _______________________________________________ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
