Paul, since you've joined this conversation and I know you implemented
state splitting in LRgen. Is the assertion that state splitting will
never completely resolve a s/r conflict correct (i.e. that there will
always be some state in the LR(1) machine that will have a s/r
conflict if the LR(0) machine has an s/r conflict? Even when I'm
certain of my logic, I prefer when someone I respect confirms it.


Thanks,
Chris
