Mill code does not contain function-call save/restore; that's all done 
for you. An interrupt is an involuntary function call, and belt and 
scratchpad are both transparently saved by the spiller. Spiller 
droppings eventually do get to memory, but you are not concerned with 
that, and only some specialized system code (like the library the 
debuggers use to probe down-stack) need care.
