Harsh developed an arith-expand compiler pass for the iree-org/iree repository, focusing on lowering ceildiv and floordiv operations into primitive arithmetic to improve LLVM lowering and hardware compatibility for NVVM and ROCm code generation. This work involved designing and integrating a dedicated pass within the MLIR infrastructure, isolating division lowering logic to reduce backend-specific edge cases and enhance maintainability. Using C++ and MLIR, Harsh ensured the new pass fit seamlessly with existing backends, laying the foundation for future GPU optimizations. The project demonstrated depth in compiler development and code generation, addressing cross-backend portability and maintainability in a focused, robust manner.

Nov 1, 2024November 2024 — iree-org/iree: Key feature delivered was the arith-expand compiler pass to lower ceildiv and floordiv into primitive arithmetic, enabling LLVM lowering and broader hardware compatibility for NVVM and ROCm code generation paths. This work was implemented with a dedicated commit (8fd3e0dd4f213393d89c6818175b67f55940b536) titled 'Add arith-expand pass to lower ceildiv, floordiv ops' (#19200). Major bugs fixed: none reported this month; efforts focused on delivering the new pass and validating integration with existing backends. Overall impact: improves portability and maintainability of division lowering across targets, reduces backend-specific edge cases, and lays the groundwork for future performance optimizations on GPUs and other accelerators. Technologies demonstrated: compiler infrastructure and passes, MLIR/LLVM-based lowering, cross-backend code generation (NVVM, ROCm), patch-based development and review.
