This function is important that we make sure when "force == false" tha we don't say that this plug-in can handle another Free BSD debugging session. I would feel better if "is_kernel()" was rock solid. See comments in that function for details https://github.com/llvm/llvm-project/pull/67106 _______________________________________________ lldb-commits mailing list lldb-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits
