Soot (software)
In static program analysis, Soot is a bytecode manipulation and optimization framework consisting of intermediate languages for Java. It has been developed by the Sable Research Group at McGill University. Soot is currently maintained by the Secure Software Engineering Group at Paderborn University. Soot provides four intermediate representations for use through its API for other analysis programs to access and build upon: * Baf: a near bytecode representation. * Jimple: a simplified version of Java source code that has a maximum of three components per statement. * Shimple: an SSA variation of Jimple (similar to GIMPLE). * Grimp: an aggregated version of Jimple suitable for decompilation and code inspection. The current Soot software release also contains detailed program analyses that can be used out-of-the-box, such as context-sensitive flow-insensitive points-to analysis, call graph analysis and domination analysis (answering the question "must event ''a'' follow event ...

Static Program Analysis
In computer science, static program analysis (or static analysis) is the analysis of computer programs performed without executing them, in contrast with dynamic program analysis, which is performed on programs during their execution. The term is usually applied to analysis performed by an automated tool, with human analysis typically being called "program understanding", program comprehension, or code review. In the last of these, software inspection and software walkthroughs are also used. In most cases the analysis is performed on some version of a program's source code, and, in other cases, on some form of its object code. Rationale The sophistication of the analysis performed by tools varies from those that only consider the behaviour of individual statements and declarations, to those that include the complete source code of a program in their analysis. The uses of the information obtained from the analysis vary from highlighting possible coding errors (e.g., the lint t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Points-to Analysis
In computer science, pointer analysis, or points-to analysis, is a static code analysis technique that establishes which pointers, or heap references, can point to which variables, or storage locations. It is often a component of more complex analyses such as escape analysis. A closely related technique is shape analysis. This is the most common colloquial use of the term. A secondary use has ''pointer analysis'' be the collective name for both ''points-to analysis'', defined as above, and alias analysis. Points-to and alias analysis are closely related but not always equivalent problems. Example For the following example program, a points-to analysis would compute that the points-to set of p is . int x; int y; int* p = unknown() ? &x : &y; Introduction As a form of static analysis, fully precise pointer analysis can be shown to be undecidable. Most approaches are sound, but range widely in performance and precision. Many design decisions impact both the precision and ...

Google Scholar
Google Scholar is a freely accessible web search engine that indexes the full text or metadata of scholarly literature across an array of publishing formats and disciplines. Released in beta in November 2004, the Google Scholar index includes peer-reviewed online academic journals and books, conference papers, theses and dissertations, preprints, abstracts, technical reports, and other scholarly literature, including court opinions and patents. Google Scholar uses a web crawler, or web robot, to identify files for inclusion in the search results. For content to be indexed in Google Scholar, it must meet certain specified criteria. An earlier statistical estimate published in PLOS One using a mark and recapture method estimated approximately 80–90% coverage of all articles published in English with an estimate of 100 million.''Trend Watch'' (2014) Nature 509(7501), 405 – discussing Madian Khabsa and C Lee Giles (2014''The Number of Scholarly Documents on the Public Web'' ...

Static Single Assignment Form
In compiler design, static single assignment form (often abbreviated as SSA form or simply SSA) is a property of an intermediate representation (IR) that requires each variable to be assigned exactly once and defined before it is used. Existing variables in the original IR are split into ''versions'', new variables typically indicated by the original name with a subscript in textbooks, so that every definition gets its own version. In SSA form, use-def chains are explicit and each contains a single element. SSA was proposed by Barry K. Rosen, Mark N. Wegman, and F. Kenneth Zadeck in 1988. Ron Cytron, Jeanne Ferrante and the previous three researchers at IBM developed an algorithm that can compute the SSA form efficiently. One can expect to find SSA in a compiler for Fortran, C or C++, whereas in functional language compilers, such as those for Scheme and ML, continuation-passing style (CPS) is generally used. SSA is formally equivalent to a well-behaved subset of CPS excludi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
