Encoding dependencies in call graphs

Abstract:

A method for modifying a call graph may include identifying, in source code, a first call site including a first predicate and a call from a first function to a second function. The first call site may correspond to a first edge of the call graph. The first edge may connect a first node corresponding to the first function and a second node corresponding to the second function. The method may further include modifying the call graph by labelling the first edge with a first encoding of the first predicate, and identifying, in the source code, a second call site including a second predicate and a call from a third function to the first function. The method may further include in response to determining that the first predicate is unsatisfied, modifying the call graph by labelling the second edge with a second encoding of a violation of the first predicate.
