Jez Ng
During October 2025, Jez Ng developed support for Mach-O 1-byte branch relocations for the x86_64 architecture in the ROCm/llvm-project repository. This work involved updating relocation attributes and refining linker logic to correctly interpret and apply smaller relocations, thereby expanding Mach-O object handling for x86_64 targets on macOS. Jez utilized low-level systems programming skills, working primarily in C++ and Assembly, to enhance the linker’s capabilities and platform coverage. The implementation required a deep understanding of compiler toolchains and Mach-O relocation modeling, resulting in more compact and robust linking for ROCm LLVM without introducing new bugs during the development period.
