Worked on enhancing cross-toolchain compatibility in the tfdsoft/famidash repository by refactoring C bindings within the famistudio assembler. Focused on reducing overhead through the use of custom macros and introduced a dedicated LLVM-MOS integration header to standardize calling conventions across multiple toolchains. This approach improved portability, performance, and maintainability, streamlining the process of building and integrating features across different compiler environments. Leveraged expertise in Assembly language, compiler toolchains, and low-level programming to deliver a solution that reduces integration friction and ongoing maintenance effort, enabling more efficient multi-toolchain development for embedded systems within the project’s codebase.
