Worked on the openjdk/leyden repository to establish a reproducible benchmarking workflow for the Java compiler, focusing on performance testing and benchmarking. The work involved migrating Javac microbenchmarks from the jmh-jdk-microbenchmarks project, enabling more granular measurement of single- and grouped-compilation stages. Java was used to implement new benchmark classes, while updates to the .gitignore file ensured that benchmark outputs did not clutter the repository. Comprehensive documentation was provided through a README, detailing build and execution steps for the benchmarks. The effort emphasized Java compiler internals and performance testing, laying groundwork for ongoing measurement and optimization within the Leyden project.
