Maybe one could use the option -ffixed-reg and put different threads in different compilation units with different options. Even so, one would not be able to use the standard library, since it is not compiled with the right options, and even custom functions would have to be compiled separately for each thread. It would be a lot of hassle, but it might work.

If you are gonna go through all that work with this chip in particular, you'd probably be better off putting four of them on one board. It's all kinda moot with more powerful chips available for cheaper anyway.

  I wasn't planning on actually doing it, I was just thinking of how it could be done.

  It's always interesting to explore how far a thing can be pushed software-wise. Copying bits is free and small AVRs are literally cents per piece in large quantities.

I think adding a custom calling convention would be the way to go.
