Fenris is a multipurpose tracer, stateful analyzer and partial decompiler intended to simplify bug tracking, security audits, code, algorithm, protocol analysis and computer forensics by providing a structural program trace, general information about internal constructions, execution path, memory operations, I/O, conditional expression info, and much more.
