WebECS 240 Data Flow Analysis 49 Where is Dataflow Analysis Useful? • Best for flow-sensitive, context-insensitive, distributive problems on small pieces of code – E.g., the examples we’ve seen and many others • Extremely efficient algorithms are known – Use different representation than control-flow Data-flow analysis is a technique for gathering information about the possible set of values calculated at various points in a computer program. A program's control-flow graph (CFG) is used to determine those parts of a program to which a particular value assigned to a variable might propagate. The … See more Data-flow analysis is the process of collecting information about the way the variables are defined and used in the program. It attempts to obtain particular information at each point in a procedure. Usually, it is … See more In 2002, Markus Mohnen described a new method of data-flow analysis that does not require the explicit construction of a data-flow graph, instead relying on abstract interpretation of … See more Data-flow analysis is typically path-insensitive, though it is possible to define data-flow equations that yield a path-sensitive analysis. • A … See more The most common way of solving the data-flow equations is by using an iterative algorithm. It starts with an approximation of the in-state of each block. The out-states are then … See more The following are examples of properties of computer programs that can be calculated by data-flow analysis. Note that the properties calculated by data-flow analysis are … See more There are a variety of special classes of dataflow problems which have efficient or general solutions.
