Someone would need to fill in the blanks in the switch statement with the x86 specific instructions. You had asked a while back how I was getting on with Tya. I got it to compile without too much difficulty. The problems since then have been in identifying the Linux specific assumptions, such as what address things will get allocated at. I think the authors know what they are doing, they just don't have any idea about writing maintainable (or portable) code. I can put a snapshot somewhere if anyone wants to look at it.
