Static Program Analysis Techniques for Software Systems

Static program analysis encompasses a suite of techniques that examine software without executing it, in order to detect defects, verify properties and guide optimisation. Fundamental approaches include control-flow analysis, which builds a graph of programme execution paths, and data-flow analysis, which tracks how values propagate through the code. Pointer and alias analyses approximate the objects to which variables may refer, enabling memory-safety checks and escape analysis for optimising memory management. Abstract interpretation provides a unifying framework by modelling program behaviours in a simplified domain, supporting flow-sensitive and path-sensitive variants that balance precision against computational cost. Demand-driven and incremental strategies have emerged to improve scalability, analysing only regions of code affected by recent changes or specific queries. Logic-programmable frameworks, often based on Datalog, enable declarative specification of complex analyses and automated fixpoint computation. More recent developments leverage graph-reachability formulations, such as Dyck languages, to capture intricate interprocedural dependencies and heap interactions. Across industry and research, these static techniques underpin security vulnerability detection, automated code refactoring, performance tuning and integrated development-environment feedback. Their global significance spans cloud services, safety-critical systems and large-scale continuous integration pipelines, where early fault detection and optimisation are essential to reducing cost and enhancing reliability.

On-the-Fly Static Analysis via Dynamic Bidirected Dyck Reachability has introduced a fully dynamic algorithm for demand-driven alias and data-dependence analyses. By modelling mutable heap data and interprocedural flows as bidirected graphs enriched with push/pop labels, it achieves near-optimal per-update performance, reducing the cost of incremental programme edits to time complexities that are effectively unnoticeable to developers and yielding speedups of up to three orders of magnitude over offline alternatives.

IntraJ: an on-demand framework for intraprocedural Java code analysis demonstrates an interactive environment that leverages Reference Attribute Grammars to perform control-flow and data-flow analyses directly within the editor. It delivers real-time feedback with typical response times under 0.1 seconds, integrating via standard language-server protocols and proving extensible through declarative specifications for new analyses and language constructs.

Flan: An Expressive and Efficient Datalog Compiler for Program Analysis reconciles the tension between expressiveness and performance by embedding Datalog in a host language using multi-stage programming. It generates specialised relational code with high-performance join strategies and custom indexing, matching or surpassing existing engines while supporting advanced features such as user-defined functions, arbitrary aggregates and lattice-based abstractions within a modular compiler framework.
