Worked on expanding watchpoint test coverage for the PPC64 architecture within the bpftrace/bpftrace repository, focusing on improving the reliability and robustness of cross-architecture testing. Leveraged C++ and system programming skills to implement architecture-aware test gating, ensuring that tests are only executed on supported platforms and thereby reducing false failures and unnecessary CI noise. Built upon previous PowerPC watchpoint support to extend the testing foundation, enhancing the quality and efficiency of the test suite. This work laid the groundwork for broader PPC coverage and contributed to more reliable validation processes, with a strong emphasis on automated testing and maintainability.
