Type system for resource bounds with type-preserving compilation

This thesis studies the problem of statically bounding the resource usage of computer programs, from programs written in high-level languages to those in assembly languages. Resource usage is an aspect of programs not covered by conventional software-verification techniques, which focus mostly on functional correctness; but it is important because when resource usage exceeds the programmer's expectation by a large amount, user experience can be disrupted and large fees (such as cloud-service fees) can be charged. I designed TiML, a new typed functional programming language whose types contain resource bounds; when a TiML program passes the typechecking phase, upper bounds on its resource usage can be guaranteed. TiML uses indexed types to express sizes of data structures and upper bounds on running time of functions; and refinement kinds to constrain these indices, expressing data-structure invariants and pre/post-conditions.
