Kaitlin Peng contributed to multiple compiler and graphics infrastructure projects, focusing on test coverage, code optimization, and documentation. In the llvm/offload-test-suite repository, Kaitlin expanded HLSL and floating-point test suites, implemented Float16 ULP-based comparisons, and enhanced ldexp and select function validation across diverse data types. She optimized the DirectX backend in intel/llvm by scalarizing integer vector operations and refining dead code elimination. Kaitlin also improved HLSL resource lowering in the arm/arm-toolchain and clarified language specifications in microsoft/hlsl-specs. Her work, primarily in C++, HLSL, and LLVM IR, demonstrated depth in low-level programming, testing, and maintainable code architecture.

October 2025 summary: Delivered architectural improvements and broader validation across three repositories, enabling more maintainable code, clearer expectations, and stronger cross-repo quality gates. Key outcomes include a modular SPIR-V combining helper, documentation alignment for HLSL intrinsics, and expanded test coverage for select across non-boolean vector conditions. Business value includes reduced maintenance costs, lower regression risk, and faster integration with downstream tooling.

June 2025 — llvm/offload-test-suite: Implemented ldexp Test Suite Enhancements, delivering cross-type coverage for Half (16-bit) and float32, including overflow/underflow edge cases, and updated test rules to BufferFloatULP to align with codebase changes after issue #217. Also fixed ldexp tests per issue #227 to ensure accurate expectations in CI.
