mcsema - Framework for lifting x86, amd64, and aarch64 program binaries to LLVM bitcode

•    C++

McSema is an executable lifter. It translates ("lifts") executable binaries from native machine code to LLVM bitcode. LLVM bitcode is an intermediate representation form of a program that was originally created for the retargetable LLVM compiler, but which is also very useful for performing program analysis methods that would not be possible to perform on an executable binary directly. McSema enables analysts to find and retroactively harden binary programs against security bugs, independently validate vendor source code, and generate application tests with high code coverage. McSema isn’t just for static analysis. The lifted LLVM bitcode can also be fuzzed with libFuzzer, an LLVM-based instrumented fuzzer that would otherwise require the target source code. The lifted bitcode can even be compiled back into a runnable program! This is a procedure known as static binary rewriting, binary translation, or binary recompilation.

weld - High-performance runtime for data analytics applications

•    Rust

Weld is a language and runtime for improving the performance of data-intensive applications. It optimizes across libraries and functions by expressing the core computations in libraries using a common intermediate representation, and optimizing across each framework. Modern analytics applications combine multiple functions from different libraries and frameworks to build complex workflows. Even though individual functions can achieve high performance in isolation, the performance of the combined workflow is often an order of magnitude below hardware limits due to extensive data movement across the functions. Weld’s take on solving this problem is to lazily build up a computation for the entire workflow, and then optimizing and evaluating it only when a result is needed.

zapcc - zapcc is a caching C++ compiler based on clang, designed to perform faster compilations

•    C++

zapcc is a caching C++ compiler based on clang, designed to perform faster compilations. zapcc uses in-memory compilation cache in client-server architecture, remembering all compilation information between runs. zapcc is the client while zapccs is the server. Each zapcc run will reuse an existing server or if none was available will start a new one. This open source release is licensed under the LLVM Release License (University of Illinois/NCSA).

jucipp - A lightweight & cross-platform IDE supporting the most recent C++ standards

•    C++

This project has moved to https://gitlab.com/cppit/jucipp. Current IDEs struggle with C++ support due to the complexity of the programming language. juCI++, however, is designed especially towards libclang with speed, stability, and ease of use in mind.

swift-llbuild - A low-level build system, used by Xcode 9 and the Swift Package Manager

•    C++

A low-level build system. llbuild is a set of libraries for building build systems. Unlike most build system projects which focus on the syntax for describing the build, llbuild is designed around a reusable, flexible, and scalable general purpose build engine capable of solving many "build system"-like problems. The project also includes additional libraries on top of that engine which provide support for constructing bespoke build systems (like swift build) or for building from Ninja manifests.

fcd - An optimizing decompiler

•    C++

Fcd is an LLVM-based native program optimizing decompiler, released under an LLVM-style license. It started as a bachelor's degree senior project and carries forward its initial development philosophy of getting results fast. As such, it was architectured to have low coupling between distinct decompilation phases and to be highly hackable. Fcd uses a unique technique to reliably translate machine code to LLVM IR. Currently, it only supports x86_64. Disassembly uses Capstone. It implements pattern-independent structuring to provide a goto-free output.

accelerate - Embedded language for high-performance array computations

•    Haskell

Data.Array.Accelerate defines an embedded language of array computations for high-performance computing in Haskell. Computations on multi-dimensional, regular arrays are expressed in the form of parameterised collective operations (such as maps, reductions, and permutations). These computations are online-compiled and executed on a range of architectures. Chapter 6 of Simon Marlow's book Parallel and Concurrent Programming in Haskell contains a tutorial introduction to Accelerate.

Hikari - LLVM Obfuscator

English Documentation Hikari(Light in Japanese, name stolen from the Nintendo Switch game Xenoblade Chronicles 2) is my hackathon-ishtoy project for the 2017 Christmas to kill time.It's already stable enough to use in production environment. However, as initially planned, Hikari has been ported to LLVM 6.0 release version and no longer being actively maintained due to the time and effort it takes. You can find the history of its development at developer branch. Further enhancements include more features like Code-Intergrity Checking and a full anti-hook implementation. These are not open-source and will probably be released as a commercial product. If you know me close enough we can discuss the license model and pricing issue because I might not be able to provide real-time bug fix and stuff. Any undiscovered potential bugs affecting the obfuscated binary are fixed during obfuscation so you get a workable binary.

This is the generator for the woboq code browser. See https://code.woboq.org for an example.

codechecker - CodeChecker is an analyzer tooling, defect database and viewer extension for the Clang Static Analyzer and Clang Tidy

•    Python

CodeChecker is a static analysis infrastructure built on the LLVM/Clang Static Analyzer toolchain, replacing scan-build in a Linux or macOS (OS X) development environment. In OSX environment the intercept-build tool from scan-build is used to log the compiler invocations.

c2goasm - C to Go Assembly

•    Go

This is a tool to convert assembly as generated by a C/C++ compiler into Golang assembly. It is meant to be used in combination with asm2plan9s in order to automatically generate pure Go wrappers for C/C++ code (that may for instance take advantage of compiler SIMD intrinsics or template<> code).You can optionally nicely format the code using asmfmt by passing in an -f flag.

gocaml - :camel: Practical statically typed functional programming language implementation with Go and LLVM

•    Go

GoCaml is subset of OCaml in Go based on MinCaml using LLVM. GoCaml adds many features to original MinCaml. MinCaml is a minimal subset of OCaml for educational purpose. It is statically-typed and compiled into a binary. This project aims incremental compiler development for my own programming language. Type inference, closure transform, mid-level IR are implemented.

ravi - Ravi Programming Language is a derivative of Lua 5

•    Assembly

Ravi is a derivative/dialect of Lua 5.3 with limited optional static typing and features LLVM and Eclipse OMR powered JIT compilers. The name Ravi comes from the Sanskrit word for the Sun. Interestingly a precursor to Lua was Sol which had support for static types; Sol means the Sun in Portugese. Lua is perfect as a small embeddable dynamic language so why a derivative? Ravi extends Lua with static typing for greater performance under JIT compilation. However, the static typing is optional and therefore Lua programs are also valid Ravi programs.

cppinsights - C++ Insights - See your source code with the eyes of a compiler

•    C++

C++ Insights is a clang-based tool which does a source to source transformation. Its goal is it to make things visible which normally, and intentionally, happen behind the scenes. It's about the magic the compiler does for us to make things work. You can see all the compiler provided functions. Also the downcast from Derived to Base.

decomp - Components of a decompilation pipeline.

•    Go

The aim of this project is to implement a decompilation pipeline composed of independent components interacting through well-defined interfaces, as further described in the design documents of the project. From a high-level perspective, the components of the decompilation pipeline are conceptually grouped into three modules. Firstly, the front-end translates a source language (e.g. x86 assembly) into LLVM IR; a platform-independent low-level intermediate representation. Secondly, the middle-end structures the LLVM IR by identifying high-level control flow primitives (e.g. pre-test loops, 2-way conditionals). Lastly, the back-end translates the structured LLVM IR into a high-level target programming language (e.g. Go).

LLVMSharp are strongly-typed safe LLVM bindings written in C# for .NET and Mono, tested on Linux and Windows. They are auto-generated using ClangSharp parsing LLVM-C header files.If you're on Windows, consider using the LLVMSharp 3.8 NuGet Package - built from LLVM 3.8 Release.

stack-guard - A toy implementation of 'Stack Guard' on top of the LLVM compiler toolchain

•    C++

A toy implementation of 'Stack Guard' on top of the LLVM compiler toolchain.Instrumentation code is added during compilation process to insert and verify stack canaries. Local variables (on the stack) are reordered to prevent buffers overflowing into other local variables. Vulnerable buffers are identified by performing a simple version of static taint analysis. Dependencies are maintained between function calls and pointer manipulations.
