This allows the unwinder to handle code with mid-function epilogues where the subsequent code is reachable through a backwards branch. Two changes are required to accomplish this: 1. Do not enqueue the subsequent instruction if the current instruction is a barrier(*). 2. When processing an instruction, stop ignoring branches with negative offsets. (*) As per the definition in LLVM's MC layer, a barrier is any instruction that "stops control flow from executing the instruction immediately following it". See `MCInstrDesc::isBarrier` in MCInstrDesc.h commit-id:fd266c13 _______________________________________________ llvm-branch-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
