Static Program Analysis: Statistics for Dummies by Engr. Michael David
Requirements: .PDF reader, 4 MB
Overview: Static program analysis is the art of reasoning about the behavior of computer programs without actually running them. This is useful not only in optimizing compilers for producing efficient code but also for automatic error detection and other tools that can help programmers. A static program analyzer is a pro- gram that reasons about the behavior of other programs. For anyone interested in programming, what can be more fun than writing programs that analyze programs?As known from Turing and Rice, all nontrivial properties of the behavior of programs written in common programming languages are mathematically undecidable. This means that automated reasoning of software generally must involve approximation. It is also well known that testing, i.e. concretely running programs and inspecting the output, may reveal errors but generally cannot show their absence. In contrast, static program analysis can – with the right kind of approximations – check all possible executions of the programs and provide guarantees about their properties. One of the key challenges when developing such analyses is how to ensure high precision and efficiency to be practically useful. For example, nobody will use an analysis designed for bug finding if it reports many false positives or if it is too slow to fit into real-world software development processes.
