Developed and integrated a P4 IR Node Transformation Hook within the p4lang/p4c repository, focusing on enhancing the extensibility of the P4 Intermediate Representation pipeline. This feature allows users and downstream tools to inject custom actions during node modifications, supporting tailored transformations and targeted optimizations. The implementation emphasized maintainable software architecture and adhered to project guidelines, with a clean, signed-off commit for improved traceability. Utilizing C++ and compiler design expertise, the work prioritized code quality and extensibility over bug fixes during the development period. The contribution enables more flexible and user-specific optimizations within the P4C transform pass workflow.
