well, there is already a lot of SDCC development happening now and
planned for the near future. While it could happen later, I wouldn't
want to make concrete plans for HC11 or 6809 ports in SDCC now. I'm
worried that planning too big could prevent us from getting anything done.
I'd suggest the following next steps:
a) MC6800, MC6801, HD6301 sdas support
b) MC6801, HD6303 uCsim support
c) mc6800, mc6801, hd6301 SDCCports
d) HC11 and MC6809 sdas support
Since AFAIK upstream asxxxx already has MC6800, MC6801, HD6301, HC11,
MC6809 support, it should be easy to port to sdas. Also AFAIK, uCsim
already has MC6800, HC11 and MC6809 support (not sure about MC6801 and
HC6303), but it is not yet in the SDCC repo.
Full HC11/MC6809 support could then be considered again, once we have
the above in place.

P.S.: I'll be quite busy with other stuff for the next few months. I
should still be able to help with c), in particular code generation and
register allocation, but won't be able to help with a), b), or d).
