Indeed. Getting rid of the dummy jumps would be one kind of optimization, and then SFN might help preserve some of the loss of location info in some cases. However, SFN doesn't kick in at -O0 because the dummy jumps and all other artifacts of unoptimized code are retained anyway, so SFN wouldn't have a chance to do any of the good it's meant to do there. -- Alexandre Oliva, freedom fighter he/him https://FSFLA.org/blogs/lxo Be the change, be Free!
