Log. 22nd April, 2013.

Over the last few days, I've been working on adding a GDB stub to XRoar. For most of that time, it's been faking responses, pretending to be running or stopped. Today it will actually stop the emulation and accept single-step (stepi) or continue instructions, as well as allow register and memory examination and modifiation while stopped.

In the process, I've added a partial m6809 target to GDB - carved out of the 68HC11 support it already has. No stack frames, and disassembly still needs a lot of work!
