- ZJIT intern integrates Iongraph for enhanced control flow graph visualization.
- Iongraph offers stable layouts, interactive navigation, and quality-of-life features like labeled backedges.
- Integration required implementing a JSON library within ZJIT due to dependency constraints.
- Computing control flow graph properties like successors, predecessors, and dominators was a key challenge.
- Used an iterative algorithm for dominator computation due to its simplicity and efficiency for small graphs.
- Natural loops and back edges were identified to compute loop depth for graph layout.
- Final implementation allows interactive exploration of optimization passes and method-level optimizations in a web browser.
- Encourages contributions to ZJIT via GitHub pull requests and community engagement on Zulip.
