Basically, we need code where the exit block is unreachable, which I believe can happen in weird cases like: ``` while(true) {...} ``` https://godbolt.org/z/rfEnfaWTv -- notice the lack of predecessors for the exit block. See the code here, which follows the ordering of the blocks and doesn't force blocks to be processed: https://github.com/llvm/llvm-project/blob/main/clang/lib/Analysis/FlowSensitive/TypeErasedDataflowAnalysis.cpp#L337-L364 Repository: rG LLVM Github Monorepo CHANGES SINCE LAST ACTION https://reviews.llvm.org/D121120/new/ https://reviews.llvm.org/D121120 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
