Worked on the rust-lang/gcc repository to enhance the reliability and accuracy of MIPS architecture validation within the GCC test suite. Focused on isolating MIPS-specific memcpy tests by restructuring test files and updating test logic, which improved test isolation and the precision of MIPS behavior validation. Later, stabilized and modernized the test suite for MIPS compact branches by updating assembler scan directives and refining expected branch instructions, ensuring compatibility with new compiler features and reducing flaky CI failures. Utilized C, assembly language, and compiler testing skills, with an emphasis on test suite development, directive management, and Git-based patching for traceability.
