RegisterContextLLDBs it contains. Previously RegisterContextLLDB objects had a pointer to their "next" frame down the stack. e.g. stack starts at frame 0; frame 3 has a pointer to frame 2. This is used to retreive callee saved register values. When debugging an inferior that has blown out its own stack, however, this could result in lldb blowing out its own stack while recursing down to retrieve register values. RegisterContextLLDB no longer has a pointer to its next frame; it has a reference to the UnwindLLDB which contains it. When it needs to retrieve a reg value, it asks the UnwindLLDB for that reg value and UnwindLLDB iterates through the frames until it finds a location. llvm-svn: 143423 |
