Summary
🤩
RockstarPhoebe Wang is a software engineer based in Shanghai with 10 years of experience specializing in low-level compiler and toolchain development. Currently at Intel, she has hands-on expertise in x86 architecture support, adding instruction set extensions like AVX512 VP2INTERSECT and ENQCMD and enabling Cooperlake/Tigerlake microarchitectures. Her open-source contributions to LLVM/Clang include SEH and debugging support improvements, APX work, and critical ABI bug fixes that ensure correct calling conventions for legacy i386 types. Phoebe combines production-grade systems development with a deep understanding of platform-specific nuances, making her a go-to engineer for performance-sensitive, architecture-level features. She brings the discipline of large-scale corporate engineering while actively contributing to one of the most influential compiler projects in the industry.

Role in this project:Back-end Developer
Back-end DeveloperContributions:12 commits in 3 months
Contributions summary:Phoebe primarily focused on modifying the Clang compiler to support new x86 instructions and address ABI-related issues. Their work involved adding support for the AVX512 VP2INTERSECT and ENQCMD instructions, as well as the -march=cooperlake and -march=tigerlake flags. Additionally, they fixed a bug in the i386 ABI related to the __m64 type, ensuring correct parameter passing and return values. This indicates a focus on low-level compiler development and x86 architecture support.
