Kazuhiro Konno has been an active contributor to the Eclipse OMR project since 2017. He has deep knowledge of both the ARMv7 and ARMv8 instruction set architectures and environments hosted on ARM processors. While his early contributions to OMR were fixes to the 32-bit ARM compiler, Konno-san's primary contributions to the OMR project are towards the development of a new AArch64 compiler backend. He is one of the principal contributors to the AArch64 code generator, and was instrumental in its design and all aspects of the implementation. He also contributed to other areas of the compiler requiring modification for compiling to an AArch64 target, as well as to the port library and makefiles. Konno-san also developed and contributed a significant number of Tril unit tests to functionally verify the evaluators that were written. As a testament to the quality of the AArch64 compiler implemented, it was used as a model by an independent group of developers to produce a compiler backend for the RISC-V processor that was recently accepted into the OMR project. As a result of his many development contributions, Konno-san has acquired deep skills in the design and implementation of the compiler and Tril infrastructure. The Eclipse OMR project would benefit from a committer with this depth of experience.
Konno-san has contributed over 199 pull requests to the project, and has repeatedly demonstrated thoroughness in his implementation, quality, and documentation of each of those commits. He has also participated in the review of 30 pull requests from other contributors. His comments always reflect respect for contributors and professionalism. When his ARM expertise is explicitly sought during a code review or through a question on Slack in the community workspace, his responses are timely and helpful. Konno-san's contributions are also aligned with the language-agnostic principles of the project as he encourages the development of language-agnostic unit test cases when appropriate and designs where language-specific aspects are isolated in consuming projects.
I believe Konno-san is an excellent candidate to be a committer in the Eclipse OMR project.
