Hmm... If that's the goal, how about adding to the mix the Statement Frontier Notes proposal I advanced in some GCC Summit? Its goal is precisely to mark user-relevant viewpoints for a debugger to stop so as at to get a consistent and progressive view of the computation. Sure enough, there are optimizations that don't make much room for that, and so it would make sense for -Og to disable those, to get excellent results, rather than just -gO0d ones ;-) > Any comments on the implementation details btw?
