> LGTM -- is there a possibility that there'll be multiple stores coming from (output arguments of?) inline asm blocks? One wonders what the desired stepping behaviour is then: arguably you want to step through all the side-effects, or some might want to just consider the inline-asm block as a single operation.

Yeah that can happen. Here I've gone for "step once on the call, step once on the last store". If we want to step on all the out-stores, that can be arranged. If you don't have a strong feeling, I can file a ticket to review this in the future once the feature is out in the wild. I'm happy with any of those outcomes
