Jomosoto contributed to the NationalSecurityAgency/ghidra repository by optimizing the TBIT instruction’s bit status evaluation, focusing on direct assessment from the source register to streamline execution and improve code clarity. Working primarily in assembly language and leveraging expertise in low-level programming and processor architecture, Jomosoto refactored the evaluation logic to reduce unnecessary checks, enhancing both performance and maintainability. The update also addressed a CR16C-specific issue, ensuring correct bit-status handling in line with CR16 requirements. This work provided a more efficient and readable codebase, supporting future enhancements and simplifying audits for developers working with TBIT-related instruction paths.
