That is correct. We aren't allowed to put state that changes in Module, so I resorted to checking PreservedAnalyses. It seems to work in this way, and adding the other classes to check doesn't change anything. All of them can be checked through this call somehow. I'm looking for another way to do this. https://github.com/llvm/llvm-project/pull/123609 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
