Worked on the kholia/zephyr repository to expand platform support and improve build reliability, focusing on Xtensa C++ exception handling and build script robustness. Enabled proper C++ exception handling on Xtensa targets by dynamically querying the compiler for the libgcc location and integrating it into the build process, ensuring exceptions are correctly supported. Addressed build script fragility by hardening syscall declaration parsing, removing newlines and normalizing whitespace to prevent formatter-induced errors. Utilized Python and CMake to implement these changes, drawing on skills in build systems, scripting, and compiler development to reduce build failures and enhance maintainability across the codebase.
