This repository runs the peggy equality saturation engine and compiler on several example files. Its purpose is to compare peggy's optimizations to eggcc, another optimizing compiler using equality saturation, on similar example files.

For the original peggy project, please refer to the peggy documentation. This is not the original peggy project.

Dockerfile Setup

The Dockerfile will clone this repository and install several dependencies.

First, build the image:

docker build -t peggy .

Now run the image.

docker run -it peggy

Comparison benchmark

This benchmark is qualitative, based on analysis of the optimized output of peggy on certain small example files. These files are in the benchmark directory.

Decompiled output for each of the benchmark Java files is stored in results. If you would like to re-generate these files, run python3 benchmark_peggy.py. In a Docker container, this took 24 min user time, 41 min total time.
