Actually, I wonder whether Daniel Berlin work will magically help? In my very rough, current understanding, should exactly help with unused members of structures and the related loads and stores, well beyond SRA... I will try to understand those things in better detail and I'd like to ask Chris to do the same: at least monitor the generated assembly until after Danny work goes in.
