Devin Papineau is an active contributor to the Eclipse OMR project in many ways. He is articulate in the design and operation of many optimizations in the common optimizer and the theory behind them. Devin has contributed nearly 70 pull requests (and nearly 100 commits) to the project, and has repeatedly demonstrated thoroughness in his implementation and quality assurance of each of those commits.
One of Devin's invaluable strengths is the thoroughness of his code and design reviews. He has formally reviewed nearly 50 PRs but has been indirectly involved in shaping many others. His reviews draw upon his deep experience with the common optimizer, Testarossa IL design and operation, optimization theory, computer architecture, C++, and debugging techniques. He often discovers missed corner cases and design limitations, and articulates his observations through clear examples when appropriate. His review comments are provided in a timely fashion and always reflect professionalism and respect for contributors.
Devin also monitors and provides responses to questions asked on the Eclipse OMR Slack workspace, particularly in areas dealing with the compiler, optimizations (e.g., inlining), or compiler IL. He is a regular participant in the OMR Architecture Meetings and offers thoughtful opinions and insights in the discussions.
All of Devin's contributions to Eclipse OMR reflect the ideals of the project and a desire to continually improve it. For example, in his reviews he encourages documentation, development of test cases, and refactoring of the code where appropriate for technical debt reduction and to realize the language-agnostic goals of the project.
I believe Devin is an excellent candidate to become a committer on the Eclipse OMR project.
