About

Aburi is a C and C++ compiler frontend with a driver named aburi. The frontend handles preprocessing, parsing, semantic analysis, compile-time evaluation, and lowering to LLVM IR.

The name comes from the town of Aburi, Ghana and its botanical garden.

Aburi uses LLVM today for IR construction, optimization, assembly/object emission, and final code generation. The driver is designed to feel familiar to GCC and Clang users, including modes such as -E, -S, -c, --emit-llvm, and -fsyntax-only.

The compiler is still early. It can already compile and run many sample programs and has been validated against a number of real-world C and C++ codebases, but silent miscompiles and incomplete language coverage are still expected.

Near-term work focuses on fixing miscompiles, expanding C++ feature coverage, improving compile-time performance and memory usage, and improving platform coverage beyond the Apple Silicon development environment.

Longer term, Aburi plans to grow a custom backend so the project can reduce its hard dependency on LLVM and explore faster non-optimizing code generation.

The project documentation notes that parts of the codebase, especially much of ast2llvm/, were generated with AI coding tools under human review, oversight, and direction. Aburi remains explicitly experimental, and the public tests, sample programs, and validation artifacts are important for judging behavior.
