• Feature Enhancements: Added support for reading AIE registers via ctrl packet configuration and SplitVectorLoadUpsChains pattern for optimizing wide vector operations.
• Code Improvements: Updated env_setup.sh, integrated python test lit config, enabled DataLayoutOpInterface, and switched to using bundled convert-to-llvm pass.
• Vectorization Optimization: Added AIEHoistVectorTransferPointersPass and AIEVectorToPointerLoops to optimize vector reads/writes and lower vector.load/store on loop-carried indices.
• Code Optimization: Added llvm-loop-opt pass to optimize generated LLVM IR and enabled recent passes in aiecc.py to optimize vectorized code’s schedule.
• Python Runtime Refinement: Refined default Python runtime sequence behavior and removed experimental code.
