Demand-driven Alias Analysis : Formalizing Bidirectional Analyses for Soundness and Precision [article]

Swati Jaiswal, Uday P. Khedker, Supratik Chakraborty
2018 arXiv   pre-print
A demand-driven approach to program analysis have been viewed as efficient algorithms to compute only the information required to serve a target demand.  ...  However, for a given set of demands, demand-driven methods are believed to compute the same information that would be computed by the corresponding exhaustive methods.  ...  ACKNOWLEDGMENTS Swati Jaiswal is partially supported by a TCS Research Fellowship.  ...

Soot-based implementation of a demand-driven reaching definitions analysis

Longwen Lu, Cheng Zhang, Jianjun Zhao
2012 Proceedings of the ACM SIGPLAN International Workshop on State of the Art in Java Program analysis - SOAP '12  
In this paper, we introduce our Soot-based implementation of an inter-procedural demand-driven reaching definitions analysis.  ...  For a demand for reaching definitions facts, the analysis only explores relevant program points and variables, saving a considerable amount of computation.  ...  In our future work, we will implement the static slicer based on a demand-driven data dependence analysis using the implementation.  ...

Simultaneous demand-driven data-flow and call graph analysis

G. Agrawal
1999 Proceedings IEEE International Conference on Software Maintenance - 1999 (ICSM'99). 'Software Maintenance for Business Change' (Cat. No.99CB36360)  
In this paper, we present an algorithm for demand-driven construction of reaching definitions, which also performs call graph analysis on a demand basis.  ...  Demand-driven analysis techniques compute data-flow fact(s) for a particular program point, rather than computing data-flow information for the entire program.  ...  Therefore, in performing demand-driven analysis, it is useful to perform call graph analysis on a demand-driven basis as well.  ...

Demand-Driven Construction of Call Graphs [chapter]

Gagan Agrawal
2000 Lecture Notes in Computer Science  
With increasing importance of just-in-time or dynamic compilation and use of program analysis as part of the software development environments, we believe that there is a need for techniques for demand-driven  ...  We use a variant of Callahan's Program Summary Graph (PSG) and perform analysis over a set of influencing nodes.  ...  In contrast, the demand-driven call graph analysis involves constructing the set of procedures called at a specific call-site, or a (small) set of call-sites.  ...

The secret sauce in efficient and precise static analysis

Eric Bodden
2018 Companion Proceedings for the ISSTA/ECOOP 2018 Workshops on - ISSTA '18  
This breakthrough, along with the use of a demand-driven program-analysis design, has recently allowed us to implement practical static analysis tools such as the crypto-misuse checker CogniCrypt, which  ...  In particular, I argue that summary-based static-analysis techniques for distributive problems, such as IFDS, IDE and WPDS have been unduly under-appreciated.  ...  Much of the research described here was first and foremost conduct by a bright set of Ph.D. students and PostDocs I had the pleasure of working with, in particular: Johannes Späth, Lisa Nguyen Quang Do  ...
