Worked on the espressif/llvm-project repository to enhance the AMDGPU backend by improving instruction scheduling and code generation. Focused on enabling commutativity for a subset of VOP3 instructions and developed preparatory tests for v_sat_pk_u8_i16 codegen, which broadened test coverage and reduced regression risk. Addressed a bug in getRegBitWidth by correctly handling SReg_256_XNULL and SReg_128_XNULL register widths, accompanied by a targeted regression test to ensure correctness. Leveraged expertise in compiler development, GPU architecture, and low-level optimization, utilizing C++, Assembly, and LLVM IR to deliver more efficient and reliable codegen for performance-critical AMDGPU targets.
