PROFILE
Filipkowski, Lukasz
Worked on the intel/intel-graphics-compiler repository, focusing on backend development and compiler design using C++ and LLVM. Delivered a feature to improve discard branch pattern matching and predicate handling for OR’ed discard masks, enhancing code generation accuracy for GPU shader compilation. Addressed floating-point conversion intrinsic bugs by introducing a helper to materialize immediates as uniform temporaries, standardizing logic across multiple conversion types for more consistent operand handling. Stabilized the CodeSinking pass by refining sink target calculations to avoid crashes in unreachable blocks, adding regression tests to reinforce reliability. Emphasized code optimization, maintainability, and robust static analysis throughout the development process.

Jun 1, 2026June 2026: Stabilized floating-point conversion intrinsics in the intel-graphics-compiler by introducing a helper to materialize immediates as uniform temporaries and standardizing the handling across multiple conversion types. This reduces incorrect operand handling and improves consistency across related conversions (e.g., hftobf8, hftohf8 fcvt), laying groundwork for broader FP intrinsic correctness and future feature work.
