GTIRB is GrammaTech's Intermediate Representation for Binary analysis and rewriting. It seeks to be for binaries what LLVM is for source - allowing researchers and developers to compose tools and leverage each other's work. GTIRB is described in a blog post, in a whitepaper, and in its manual.
We have built an ecosystem of tools around GTIRB, many of them available as open source and listed in the table below. In brief, our disassembler DDisasm generates GTIRB from binaries, while GTIRB-PPrinter can pretty-print GTIRB as assembly or as a binary executable. A variety of analyses run top of GTIRB, such as Retypd for binary type recovery. The gtirb-rewriting API supports modifying GTIRB files. It forms the foundation for a number of transforms that harden, optimize or debloat binaries, such as gtirb-stack-stamp and to-static. GTIRB-VSCode allows developers to work with GTIRB files in the VSCode IDE, while gtirb-ghidra-plugin suports Ghidra integrations.
GTIRB-based tools that are not open source are available to approved users via the GTIRB Omnibus image v 0.2.0.
