That's the same approach that gets you from 2 to 1 clobbered registers for stores, no? i.e. usually possible, but needs compiler participation; if assuming the compiler will optimize load register usage properly, it shouldn't have any problem reducing the store clobbers from 2 to 1 either, which I understood as the difficult part. (or course 1 clobber is still worse than 0, but at least it means no 2 writes/fused instr, at least here)
