February 2026 monthly summary for Xilinx/onnx-mlir focusing on delivering maintainable code, broader model compatibility, and correctness improvements across the ONNX-MLIR stack. The month emphasized bug fixes, performance-related refactors, and scalable code quality improvements that reduce downstream risk and accelerate development cycles.

January 2026 highlights for Xilinx/onnx-mlir: Delivered performance-oriented optimization and transformation passes (Slice, StridedSlice, Concat, Conv) with migration from the flexml project, plus updated tests for channel-last and transposed conv configurations; strengthened shape inference and resize handling to ensure correct types and outputs across missing ops; added dilation attribute for average pooling to expand model configurability; completed code style cleanup and clang fixes to improve maintainability. Major bug fix: quantization correctness and type preservation where DequantizeLinear feeding into transpose/reshape could inadvertently introduce quant types; implemented pattern checks and related revert/adjustments to stabilize quantization across model outputs. Overall impact: more reliable quantized inference, improved performance through optimized passes, broader test coverage and maintainable codebase, enabling smoother future changes. Technologies and skills demonstrated: C++/clang code quality, compiler optimization passes, ONNX-MLIR architecture, shape and type inference, test-driven development, cross-repo collaboration.
