PROFILE
Xin Wang
Wang Xin enhanced LoongArch support in espressif/binutils-gdb by improving linker error reporting, providing clearer diagnostics and actionable guidance when relocations are misused with shared objects or PIE executables. Using C and linker scripting, Wang added targeted tests to ensure reliability of these messages, streamlining debugging for developers. In openssl/openssl, Wang addressed cross-architecture build failures by replacing la.pcrel with la.global in assembly code, aligning with stricter binutils requirements and enabling successful OpenSSL shared library builds on LoongArch. This work demonstrated expertise in low-level programming, ELF format, and compiler development, delivering robust, maintainable solutions for complex toolchain issues.

Jan 1, 2025January 2025: Cross-arch build stability for OpenSSL on LoongArch. Implemented a compatibility fix replacing la.pcrel with la.global to satisfy stricter binutils checks, enabling successful builds of OpenSSL shared libraries. Result: reduced CI failures, faster releases, and stronger deployment readiness on LoongArch systems. Demonstrates cross-arch tooling, linker and binutils expertise, and maintainable patch workflow.
