These days multi-core chips are unavoidable, more executions needs to be done in parallel and problems become extremely difficult to debug. Upcoming GDB features will facilitate multi-core debugging: global breakpoints with kernel module, PTC sets debug control, target side thread/core bkp/tcp, auto-disabling breakpoints, detection of thread core affinity error, dynamic-printf. Furthermore, the amount of asynchronous data cannot be handled via the cmd line anymore. The Eclipse Multi-Core Debugging Work Group are thus developing the multicore visualizer, dynamic grouping of cores/processes/threads, pinning/cloning of debugging views, GDB events and are synchronizing with the GDB cmd line.
In addition, existing multi-core features will be described e.g. non-stop, multi-process, reversible-debugging, tracepoint and LTTng UST markers. A must for anyone who has to debug multicore systems.
