It's technically possible to have a signal handler that consumes SIGILL and then jumps over the offending instruction. The UBSan docs allude to this: "-fsanitize-trap=...: execute a trap instruction (doesn’t require UBSan run-time support). If the signal is not caught, the program will typically terminate due to a SIGILL or SIGTRAP signal." (https://clang.llvm.org/docs/UndefinedBehaviorSanitizer.html) That said, I agree that it is extremely likely the trap only happens once. https://github.com/llvm/llvm-project/pull/134310 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
