PROFILE
Chen
Worked on expanding AARCH64 instrumentation capabilities in the DynamoRIO/dynamorio repository, focusing on broadening platform coverage and improving observability for ARM workloads. Developed memory-based and conditional branch instrumentation for the AARCH64 architecture, extending the cross-architecture instrumentation framework to support more reliable performance analysis. Implemented AARCH64-specific instruction creation macros and updated existing macros to handle instructions such as ubfm and csinc, ensuring correctness and testability on hardware. Enhanced and expanded test suites, including count-ctis, instrcalls, and cbrtrace, to validate new features. Utilized Assembly and C, applying expertise in low-level and system programming, compiler development, and ARM architecture.
