gcc6809 actually does a remarkable job when optimization for size is 
enabled. It could probably do a much better job with some tweaking but 
that's a harder job than it looks like (I've tried). The biggest problem 
with the most recent "official" version of gcc6809 is that it does not 
build properly on a 64 bit linux platform - it has issues related to 
word size - and porting it forward to a newer version of gcc is not 
pleasant due to some massive changes to the gcc internals.
