During the month, contributed to the ROCm/llvm-project repository by implementing support for Mach-O 1-byte branch relocations on the x86_64 architecture. This work involved updating relocation attributes and refining linker logic to correctly interpret and apply smaller relocations, thereby expanding Mach-O object handling for macOS targets. The technical approach required in-depth knowledge of low-level systems programming, linker development, and the x86_64 architecture, utilizing both C++ and Assembly. By enhancing the linker's capabilities to handle compact relocations, the contribution strengthened platform coverage for ROCm LLVM and improved the robustness and flexibility of object file linking on supported systems.
