In step three we use symbolic execution to syn-thesize the weakest relation on program states that guarantees indistinguishability in the observational model (Sect. Through this relation, the observational model is used to drive the generation of test cases -pairs of states that satisfy the relation and can be used as inputs to the program (Sect. The following observational model attempts to overapproximate information flows for data-caches by relying on the fact that accessing two different addresses that only differ in their cache offset produces the same cache effects: Notice that by making the program counter observable, this model assumes that the attacker can infer the sequence of instructions executed by the program.	./cache/cord-029311-9769dgb6.txt	./txt/cord-029311-9769dgb6.txt
