Nytro Posted November 3, 2011 Report Posted November 3, 2011 REC - Reverse Engineering CompilerFeatures As mentioned, Rec Studio 4 is still under development. Most target independent features have been completed, such as: Multihost: Rec Studio runs on Windows XP/Vista/7, Ubuntu Linux, Mac OS X. Symbolic information support using Dwarf 2 and partial recognition of Microsoft's PDB format. C++ is partially recognized: mangled names generated by gcc are demangled, as well as inheritance described in dwarf2 is honored. However, C++ is a very broad and difficult language, so some features like templates won't likely be ever supported. Types and function prototype definitions can be specified in text files. Some standard Posix and Windows APIs are already provided in the Rec Studio package. Interactivity is supported, limited to definition of sections, labels and function entry points. Will need to improve it to support in-program definition of types and function parameters. Although REC can read Win32 executable (aka PE) files produced by Visual C++ or Visual Basic 5, there are limitations on the output produced. REC will try to use whatever information is present in the .EXE symbol table. If the .EXE file was compiled without debugging information, if a program data base file (.PDB) or Codeview (C7) format was used, or if the optimization option of the compiler was enabled, the output produced will not be very good. Moreover, Visual Basic 5 executable files are a mix of Subroutine code and Form data. It is almost impossible for REC to determine which is which. The only option is to use a .cmd file and manually specify which area is code and which area is data.In practice, only C executable files produce meaningful decompiled output.
