Worked on the golang/arch repository to enhance the reliability and accuracy of RISC-V objdump testing. Focused on stabilizing riscv64 objdump tests by ensuring ELF files consistently included the .riscv.attributes section and refining test logic to accommodate expected mismatches. Updated the .riscv.attributes content to accurately reflect specific RISC-V extensions, which improved the alignment of objdump output with actual architecture features. Employed Go for implementation, leveraging skills in assembly language and compiler development, and emphasized thorough testing. All changes were carefully reviewed and documented, with attention to code quality and ensuring no regressions outside the targeted RISC-V objdump tests.
