Separation Logic is a widely used formalism for describing dynamicallyallocated linked data structures, such as lists, trees, etc. The decidabilitystatus of various fragments of the logic constitutes a long standing openproblem. Current results report on techniques to decide satisfiability andvalidity of entailments for Separation Logic(s) over lists (possibly withdata). In this paper we establish a more general decidability result. We provethat any Separation Logic formula using rather general recursively definedpredicates is decidable for satisfiability, and moreover, entailments betweensuch formulae are decidable for validity. These predicates are general enoughto define (doubly-) linked lists, trees, and structures more general thantrees, such as trees whose leaves are chained in a list. The decidabilityproofs are by reduction to decidability of Monadic Second Order Logic on graphswith bounded tree width.
