This is currently in-development vaporware.

Graf is a graph-oriented compiler infrastructure written in Zig. Chiefly, it provides the Graph Code intermediate representation, a simple optimization framework, and a machine code generator.

Graph Code is based on the RVSDG, a novel IR that has a number of desirable properties such as explicit data and state dependencies, inherent static-single assignment form, strong canonicalization, and whole-program representation.

Optimization is primarily based on e-graphs and equality saturation. In addition to being a natural fit for the RVSDG, this results in a cohesive framework for discovering rewrites and losslessly adding them to the IR, thus avoiding the phase-ordering problem.
