Documentation

SVF is a static value-flow analysis tool for LLVM-based languages. SVF (CC'16) is able to perform

• WPA (whole program analysis): field-sensitive (SAS'19), flow-sensitive (CGO'21, OOPSLA'21) analysis;
• DDA (demand-driven analysis): flow-sensitive, context-sensitive points-to analysis (FSE'16, TSE'18);
• MSSA (memory SSA form construction): memory regions, side-effects, SSA form (JSS'18);
• SABER (memory error checking): memory leaks and double-frees (ISSTA'12, TSE'14, ICSE'18);
• MTA (analysis of mutithreaded programs): value-flows for multithreaded programs (CGO'16);
• CFL (context-free-reachability analysis): standard CFL solver, graph and grammar (OOPSLA'22, PLDI'23);
• SVFIR and MemoryModel (SVFIR): SVFIR, memory abstraction and points-to data structure (SAS'21);
• Graphs: generating a variety of graphs, including call graph, ICFG, class hirachary graph, constraint graph, value-flow graph for static analyses and code embedding (OOPSLA'20, TOSEM'21)

SVF's doxygen document is available here.

We are looking for self-motivated PhD students and welcome industry collaboration to improve SVF (Please contact [email protected])

We release SVF source code in the hope of benefiting others. You are kindly asked to acknowledge usage of the tool by citing some of our publications listed http://svf-tools.github.io/SVF, especially the following two:
