Worked on the Samsung/TizenRT repository to deliver a cross-compiler macro, GET_RETURN_ADDRESS, implemented in C within compiler.h. This macro captures the caller’s return address in a compiler-independent manner, standardizing return address logging across GCC and other toolchains. The approach enhances debugging utilities and memory management by providing consistent return address information, which improves crash analysis and traceability. By focusing on compiler development and embedded systems, the work reduced debugging time and enabled future profiling features. The solution increased cross-compiler portability for TizenRT, supporting more robust operating system diagnostics without introducing new bugs during the development period.
