A generic framework for heap and value analyses of object-oriented programming languages
No full textAbstract interpretation has been widely applied to approximate data structures and (usually numerical) value information, but their combination is needed to effectively apply static analysis to real software. In this context, we introduce a generic framework that, given a heap and a value analysis, combines them, proving formally its soundness. We plug inside this framework a standard allocation site-based pointer analysis, a TVLA-based shape analysis, and standard existing numerical domains. As far as we know, this is the first sound generic automatic framework for statically typed object-oriented programming languages combining heap and value analyses that allows to summarize and materialize heap identifiers
Patologie rare dell'orecchio
Full text linkAfter fifty years of experience, mostly spent in ENT surgery
at the University of Palermo, I have pleasure in presenting
this Atlas of rare diseases of the ear, including clinical cases
observed and documented during this long period from 1958
to 2006.
We would prefer to divide all the case studies into three chapters:
the outer ear, middle ear and inner ear
Welcome from the Chairs
No full textThe 12th ACM SIGPLAN International Workshop on the State Of the Art in Program Analysis (SOAP ’23) is co-located with the 44th ACM SIGPLAN International Conference on Programming Language Design and Implementation (PLDI ’23). In line with past workshops, SOAP ’23 aims to bring together the members of the program analysis community to share new developments and shape innovations in program analysis
SARL: OO Framework Specification for Static Analysis
No full textSemantic static analysis allows sound verification of program properties, that is, to prove that a given property holds for all possible executions. However, modern object-oriented applications make heavy use of third-party frameworks. These provide various functionalities (like libraries), as well as an extension of the execution model of the program. Applying standard models to statically analyze software relying on such frameworks could be potentially unsound and imprecise. In this paper we introduce SARL, a domain-specific language which allows one to specify the runtime behaviors of frameworks of object-oriented programs. Such specifications can be then applied to automatically generate annotations on program components of the application to model the framework runtime environment. In addition, SARL specifications document which aspects of a framework are supported by the static analyzer and how. We adopted SARL to model WindowsForms and ASP.NET, two of the most popular.NET frameworks in an existing industrial static analyzer (Julia). We then analyzed the three most popular GitHub repositories using these frameworks, comparing the results with and without SARL. Our experimental results show that the application of SARL sensibly improved the precision and soundness of the analysis without affecting its runtime performances
Static analysis via abstract interpretation of the happens-before memory model
No full textAbstract. Memory models define which executions of multithreaded programs are legal. This paper formalises in a fixpoint form the happens-before memory model, an over-approximation of the Java one, and it presents a static analysis using abstract interpretation. Our approach is completely independent of both the programming language and the analysed property. It also appears to be a promising framework to define, compare and statically analyse other memory models
