Don't all laugh at once, but I've been wondering about hooking GDB up to some emulators, and perhaps even adding debugging support to one of the Z80 C compilers to use with GDB. I can imagine that this would be a pretty big task, though. What got me thinking about this is the Z80 target for QEMU that I've been writing. QEMU is an emulator that uses dynamic recompilation to convert emulated code into machine code appropriate for the system that it is running on. QEMU provides support for debugging emulated machines using GDB -- however, GDB lacks remote debugging support for the Z80. BTW, if anyone's interested in this: http://homepage.ntlworld.com/wholehog/stuart/qemu/index.html Currently, it only emulates the 48K Spectrum, but I would welcome patches to fix bugs or add features (such as SAM emulation :-) (BTW, I am not especially interested in emulating undefined behaviour at this point, nor am I interested in accurate timings.)
