February 2026 monthly summary for xdsl project (xdsl). This period delivered and integrated major enhancements to mathematical optimization passes and hardware dialect capabilities, establishing a stronger foundation for high-performance floating-point workloads across environments with varying hardware support.

Month 2025-01: Implemented major LLVM dialect enhancements in the xdsl repository, focusing on expanding interoperability with LLVM IR and enabling richer numeric operations. Delivered a BitcastOp for casting between LLVM-compatible non-aggregate types, added a suite of floating-point instructions (fadd, fsub, fmul, fdiv, frem, sitofp, fpext), and included comprehensive tests along with updates to dialect list sorting. These changes establish a stronger foundation for LLVM-backed code generation and future optimizations, while increasing test coverage and reliability.

December 2024 summary for KULeuven-MICAS/snax-mlir: Delivered SNAX Accelerator Tracing Enhancements, extending the tracing script with SNAX-specific events, integrating trace_to_perfetto for detailed accelerator analysis, enabling sequential tracing for debugging, and supporting multiple SNAX accelerators for event generation. Major bugs fixed: none reported in this period; tracing tooling stability improved. Overall impact: improved observability, faster performance diagnosis, and a stronger foundation for optimizer work on SNAX workloads. Technologies/skills demonstrated: Python scripting for instrumentation, Perfetto tracing integration, debugging workflows, and multi-accelerator configuration management. Commit reference: e7c4c346b3f80a748c035b303c62e083628d79ad.

November 2024 highlights: Delivered ACCFG dialect enhancements with granular launch configs and side-effect modeling, aligning with snax-mlir and improving readability of launch/setup operations; this work includes a targeted commit updating the dialect to match the snax-mlir version (#3429).
