- SVF now supports analysis for C++ programs.
SVF is a static tool that enables scalable and precise interprocedural dependence analysis for C and C++ programs. SVF allows value-flow construction and pointer analysis to be performed iteratively, thereby providing increasingly improved precision for both.
SVF accepts the points-to information generated by any pointer analysis (e.g., Andersen’s analysis) and constructs an interprocedural memory SSA form so that the def-use chains of both top-level and address-taken variables are captured. SVF is implemented on top of an industry-strength compiler LLVM (version 6.0.0). SVF contains a third party software package CUDD-2.5.0 (Binary Decision Diagrams (BDDs)), which is used to encode path conditions.
