    8cc C Compiler

    8cc C Compiler

    Compiler for the C programming language

    8cc C Compiler is a small and educational C compiler designed to support the C11 standard while maintaining a compact and easy-to-understand codebase. It was created as a hobby project with the goal of demonstrating how a compiler works internally, making it a valuable resource for learning compiler design. The project includes core components such as a lexer, parser, and preprocessor, allowing users to explore each stage of the compilation process. One of its notable features is its ability to compile itself, showcasing its completeness and serving as a practical example of bootstrapping in compiler development. The code is intentionally written to be concise and readable, making it accessible to developers who want to study compiler internals. Although it lacks advanced optimization features and is not intended for production use, it provides a solid foundation for understanding how C programs are translated into machine code.

    9cc C compiler

    9cc C compiler

    A Small C Compiler

    9cc is a small and educational C compiler designed to demonstrate the internal workings of a compiler while still being capable of compiling meaningful programs. It serves as a continuation of Rui Ueyama’s series of compiler projects, focusing on clarity and incremental development rather than production-level optimization. The compiler implements essential stages such as lexical analysis, parsing, semantic analysis, and code generation, providing a complete pipeline from source code to executable output. It supports a subset of the C language sufficient to understand real-world compilation concepts, making it a valuable learning resource for developers interested in low-level programming. The project emphasizes readability and simplicity, with code structured to be easily understood rather than highly optimized. It also demonstrates key compiler design principles such as abstract syntax trees and symbol tables.

    The software generates automatically concurrency control code based on a given specification. Specifications consist of a description of the concurrency constraints, a state machine description of the processes and/or threads that are to be coordinated, and the C code associated with each state of the state machines. The output of the software is a C program containing the implementation of the concurrency constraints and the segments of code given in the specification.

    Alchemist plugin

    Alchemist GCC/LLVM plugin for code analysis and tuning

    News: since 2015 we continue all related developments within Collective Knowledge Framework: http://github.com/ctuning/ck/wiki Alchemist plugin is a collection of plugins for GCC/LLVM for external and fine-grain code analysis and tuning. It is intended to to extract program properties for machine learning based optimization (see MILEPOST GCC); optimize programs at fine-grain level (such as unrolling, tiling, prefetching, etc); tune default optimization heuristic; gradually decompose program and detect performance or other anomalies; generate benchmarks particularly useful to train ML-based compilers. GCC plugin is licenced under GPLv3 licensed, while future LLVM plugins will be licensed under BSD license. Alchemist plugin is in a preliminary stage (based on MILEPOST ML plugin), so collaborations are very welcome!

    E Integrated Development Environment Targeting All Systems

    NOTE: Project has been delayed due to other tasks. I will return to this project in 2018. This is a new project which will be available soon. I wanted to bring AmigaE back to life, so I wrote an E to C transpiler which creates C code compatible CC65/CMOC/VBCC/BCC/GCC/TCC/LCC etc. The aim is to bring AmigaE to every possible platform in one hit.

    AppM Build Automation

    AppM Build Automation

    Automated software application for constructing and building projects.

    AppM Build Automaiton is an open source and automated software application that is used to construct and build projects on different operating systems and using different development environments. General principles of implementation: -Each project must have a Build Project File, containing the necessary information on the construction of the project. For example, a unique name of the project, dependence on other projects and libraries, methods of construction, etc. Thus, the entire repository should be marked by the project description files to provide unambiguous information on the projects and their dependencies. - AppM Build Automaiton must be able to perform different actions (project construction, external applications launch, file copying, etc.) which are needed to build a -product. - All operations with projects should be carried out on the basis of information that build tool derives from the project description files.
