> This makes sense. Only volatile registers which are allocated need to be saved and restored. You could also use `is_volatile()` functions from the `Register` class. The registers which are not allocated should not show up here because we get them from `live_regs_iterator.next()`. So, I think there's no need to filter them out. But you can filter them out. I have no objects. I had basically asked because of readability reasons. Sorry if my question was a bit confusing.

No I guess your question was perfectly correct. My concept for "which register needs to be preserved" was a bit on the loose. But now I got idea. So thanks for that.
