Control Dependence Graph and Data Dependence Graph
A Control Dependence Graph (CDG) and a Data Dependence Graph (DDG) are essential tools in computer science, particularly in compiler design and program analysis. They represent the dependencies between different parts of a program's code, but they focus on two distinct types of relationships. Control Dependence Graph (CDG) A Control Dependence Graph illustrates how the execution of a statement is controlled by a conditional branching statement. In simpler terms, a statement is control-dependent on a conditional if the outcome of that conditional determines whether the statement will be executed. Nodes in a CDG represent the…
