PROFILE
Chen
Jiege Chen expanded AARCH64 instrumentation capabilities in the DynamoRIO/dynamorio repository, focusing on broadening platform coverage and improving observability for ARM workloads. He implemented memory-based and conditional branch instrumentation for the AARCH64 architecture, introducing new instruction creation macros and extending existing ones to support instructions such as ubfm and csinc. Using C and Assembly, Jiege enhanced the cross-architecture instrumentation framework, ensuring correctness and testability on AARCH64 hardware. He also updated and expanded tests, including count-ctis, instrcalls, and cbrtrace, to validate the new features. The work demonstrated depth in low-level and system programming for compiler development.
