Gradual Verification of Recursive Heap Data Structures
Static verification tools for recursive heap data structures impose significant annotation burden on developers. This is true even when verifying a simple function that inserts an element at the end of a linked list. Gradual verification was introduced to allow developers to deal with this burden incrementally, if at all. It draws from research on gradual typing to produce a verification system that supports imprecise specifications along a continuum. However, current gradual verification technology can only support a simple first-order specification logic. This paper outlines work in progress on an extension to gradual verification that supports implicit dynamic frames and recursive abstract predicates using examples. This paper also highlights challenges and proposes solutions to verifying such examples.
