I would have no idea how to list all STM8 variants on the ST website; AFAIK one can only easily list those marketed under the STM8 name. And for some, I can't even find sufficient documentation to support them in teh free tools (e.g. the STWBC). > > A while ago I did some experiments (sadly not completed yet) by adding a 24 > bit mode to the SDCC STM8 port.

I suggest you have a look at current SDCC trunk. Since you already have some experience with 24-bit space support, you might be able to provide patches for the still-missing parts.
