joeq is a Java 2 (JDK 1.3 and 1.4) compatible virtual machine. It is unique in that it is entirely implemented in Java, leading to greater reliability, portability, maintainability, and efficiency. It is also language-independent, so code from any supported language can be seamlessly compiled, linked, and executed dynamically.
The GCC XML Tree Node Introspector project consists of a patch to the gcc compiler to output the internal compiler tree nodes in RDF/XML and programs to process that RDF/XML. The tree nodes are complex data structures which represent the source code inside the compiler. Through these tree nodes, users are able to extract information from their programs that would be otherwise very difficult to obtain. Modules exist to store these nodes in Redland RDF using a Berkley database. The long-term goal of the project is create a high-level API that will make the programmatic manipulation of programs easier than it is now.
Chump is a table-driven assembler and dissembler with a very fast new architecture input format. Both the assembler and disassembler are created using a single description. It comes with descriptions for ARM, MIPS, Stump, and 6809. It is intended for use as a library compiled with other programs to allow line assembly and disassembly.
Classfile Reader & Writer is a Java package that makes it easy to read and write Java class files. It does not provide any help with displaying the contents of a class file (besides debug output) or disassembe the byte codes, but can read "obfuscated" class files such as those generated by Crema.
REC is a portable reverse engineering compiler, or decompiler. It reads an executable file and attempts to produce a C-like representation of the code and data used to build it. It can decompile 386, 68k, PowerPC, and MIPS R3000 programs. It recognizes the following file formats: ELF (System V Rel. 4, e.g. Linux, Solaris, etc.), COFF (System V Rel. 3.x, e.g. SCO), PE (Win32 .EXE and .DLL for Microsoft Windows 95 and NT), AOUT (BSD derivatives, e.g. SunOS 4.x), Playstation PS-X (MIPS target only), and raw binary data (via .cmd files).
