PROFILE
Hank Chang
Hank Chang enhanced AddressSanitizer support for RISC-V Vector (RVV) operations in the llvm/llvm-project repository, focusing on both instrumentation improvements and expanded feature coverage. He consolidated RVV instrumentation by relocating memory operand analysis to a more maintainable layer and embedded it within core data structures, enabling more accurate detection of memory errors in vectorized code. Hank implemented support for complex RVV segment load/store intrinsics, treating segments as large integers to improve memory access tracking. Using C++ and LLVM IR, he also developed comprehensive tests for various RVV configurations, ensuring correctness and reliability for memory safety in low-level RISC-V workloads.
