Title: Formally-verified Space Safety for Optimizations

Abstract: Program optimizations are typically expected to be sound, meaning that they do not change program behavior. Their impact to improve program performance is tested, but not proven; and it is possible to even worsen asymptotic behavior. In this work, I proved that changing allocation point of objects maintains the space usage of the program, assuming careful management of closures. The critical contribution was proving this relation despite a many-to-one relations of the program heaps.
