Program analysis: interprocedural analysis
WebLecture 9: Datalog with Negation 9-3 Notice that (P2) defines the IDB R, and (P3) defines TC; TC has a negated IDB in the body of a rule that defines it, but this IDB appears in the previous stratum (P2). A Datalog:program can have many possible stratifications.For instance, in the above example we could switch the order of (P1), (P2) and still get a … WebDatalog is a declarative logic programming language. While it is syntactically a subset of Prolog, Datalog generally uses a bottom-up rather than top-down evaluation model. This difference yields significantly different behavior and properties from Prolog. It is often used as a query language for deductive databases. WebThe core of the compiler is a Futamura projection that translates a declarative Datalog program to an executable imperative C++ program via partial evaluation. Soufflé aims to support designers of program analyses and to increase their productivity, i.e., enabling rapid prototyping for static program analysis, and making deep design-space ... nik architect
