Release notes:

The major feature in this release are the changes to Reko to support the use
of native code disassemblers, and potentially any other low-level libraries
that may prove beneficial such as symbol parsers and code emulators. The
Reko build system was modified to allow the compilation of C++ code that interfaces
between low-level libraries and the other, managed parts of Reko. The immediate
benefits of these changes are the much improved support for the ARM processor
architecture and (finally) the possibility of running Reko in 64-bit mode.

This is the first release where a 64-bit MSI installer is available for Windows
users. Non-Windows users can now choose whether to build a 32- or a 64-bit version
of Reko. With the expanded address space, the 64-bit version will be able to handle
larger binaries than the 32-bit version.

Another area of large improvements is the generation of structured C code. Reko's high-level
output is now much improved.

Some other changes of note:

  • Improved TRAP and A-line instruction support for MacOS Classic.
  • General improvements for MacOS classic and M68k support.
  • Impelemented a Pascal parser to handle MacOS MPW header files.
  • Improved support for Intel HEX files.
  • Support for DEC Alpha and AVR8 architectures.
  • Support for many more x86 SSE instructions, initial support for AVX instruction types.
  • Finally merged PR from @Lukas-Dresel to improve support for MIPS-64.
  • Parallelized regression suite script across processes; this sped up the output by a factor of 5.
  • Support for Borland symbol information.
  • Moved project to C# 7 and .NET framework 4.7.
  • Fixed bugs in the Type inference affecting recursively defined types.

Thanks to @dmakarov, @Lukas-Dresel, @Kalmalyzer, @VladRassokhin, @gbody, @chostelet
for their contributions. Special thanks to @ptomin and @smx-smx for their code, time, and devotion.

The big feature of this release is the adaptation and implementation of the shingled disassembler and procedure detection algorithms described in the papers "Shingled Graph Disassembly: Finding the Undecidable Path" by Richard Wartell, Yan Zhou, Kevin W.Hamlen, and Murat Kantarcioglu ( and "Compiler-Agnostic Function Detection in Binaries", by Dennis Andriesse, Asia Slowinska, Herbert Bos ( A clone of the source code from the latter is located here:

These optional analyses vastly improve Reko's discovery of executable code, at the cost of increased memory and time consumption. Because of the cost, they must be explicitly requested. In the GUI client, this is done by right-clicking on a loaded program node, selecting the Properties menu item, switching to the Scanning tab and selecting "Shingled scanning". From the command line, the following incantation will do the job:

    decompile --heuristic shingle binary.exe

Some other goodies are also part of this release:

  • Added support for the Super-H, TLCS-90, and TLCS-900 processor architectures.
  • Added support for the SEGA DreamCast, and NeoGeo platforms
  • Added a front end that can load LLVM .ll files and transpile them into Reko IR. Special thanks for @mewmew for his assistance
  • Added an Intel HEX file front end.
  • The usual large number of bug fixes

Thanks to @ptomin, @Kalmalyzer, and @smx-smx for their contributions.

This minor release focuses on stabilization, but a few major features have made it as well:

  • Implemented a general varargs processing mechanism, and specific instances for standard C printf and scanf function families, as well as the Py_BuildValue function from the Python runtime.
  • Early support for dealing with indirect function calls.
  • Improved ELF support for x86, x86-64, MIPS, PowerPC, ARM, and Sparc
  • Improved PE support for x86, x86-64, MIPS, and ARM
  • Added support for lifting more instructions in x86, M68k, VAX, Sparc, MIPS, Z80 architectures.
  • Beginning support for signature libraries.
  • The cancel button actually works now!
  • Support for "No decompile"
  • General bugfixes

Special thanks to @ptomin, @nemerle, @mewmew, @xor2003, @Lukas-Dresel for their contibutions.

At last, a new major release! Большое спасибо to @ptomin, who put in an amazing amount of effort to bring you:

  • Combined code and low-level viewer, to allow users to compare Reko's output with the original binary.
  • Improvements in user-specified data types

In the eye candy department:

  • A graph viewer, to help users to visualize procedure call graph (thanks to @halsten for the suggestion)
  • Image map view shows an overview of the image bytes as pixels
  • Allow user to specify the encoding used for text when displaying character data

And the nuts and bolts work:

  • New reko configuration and project file formats
  • More MIPS instructions supported
  • SPARC support greatly expanded
  • Added initial support for DEC VAX processor architecture
  • Support for SEGA Genesis platform added
  • Much better support for ELF binaries, both executables and relocatable object files
  • Refactored central ImageMap class to support binaries with large address space "gaps"

Because of the major changes that have taken place, it's likely that Reko may be unstable after all the major surgery. If you encounter any issues while running Reko, please report them in the issue tracker.
