The in_call_stack Python script makes it possible to modify the last breakpoint to only stop if a given function is present in the call stack. It will check both the symbol name and the function name (coming from the debug info, in case the binary is stripped). To use this, you have to: 1. Import the script into lldb. (lldb) command script import in_call_stack.py 2. Set a breakpoint and use the in_call_stack alias. (lldb) b foo (lldb) in_call_stack bar Note that this alias operates on the last set breakpoint. You can re-run the in_call_stack command to modify the condition.
