Worked on the DynamoRIO/dynamorio repository to enhance AArch64 ptrace functionality by implementing full register state copying, including SIMD and status registers, during injection. This approach improved the reliability and correctness of instrumentation workflows by ensuring state consistency, supported by an integrity test that verifies register states before and after attach. Additionally, addressed a type warning in the attach_state test by updating data types to uint64_t, improving cross-architecture compatibility and CI stability. The work demonstrated strong skills in C and C++ development, assembly language, low-level debugging, and systematic testing, with a focus on robust system programming and maintainable code integration.

Nov 1, 2025Month 2025-11 summary for DynamoRIO/dynamorio: fixed a type warning in the attach_state test by using uint64_t to align with u128_to_2xu64, improving test correctness and cross-architecture compatibility. This bug fix reduces CI noise, improves test reliability, and supports stable integration with 128-bit helpers. Commit i#7577 (#7706) eb5bd836f7dd882b42a0c751999fde526218969c.

Oct 1, 2025October 2025 monthly summary for DynamoRIO/dynamorio: Delivered a targeted AArch64 ptrace improvement and expanded test coverage to ensure robustness of the injection path. The changes copy the full register state (including SIMD and status registers) during ptrace injection and introduce an integrity test to verify state consistency before and after attach, reducing the risk of state drift in instrumentation workflows. This work is tracked under i#7577 with commit bae223e9da469337c5ddc782c73d9845907d199f (#7696). No major bug fixes were recorded this month. Overall, this enhances reliability of AArch64 instrumentation and demonstrates strong low-level debugging capabilities, test automation, and Git workflow discipline.
