mlir-development

# MLIR development Define the source and target invariants for each dialect boundary before implementing rewrites or lowering. ## Topic routing - [Foundations](references/foundations.md) for MLIR's IR model, dialects, operations, types, and attributes. - [Passes and conversion](references/passes-and-conversion.md) for transformations, patterns, legality, and lowering. - [Dialects and compilers](references/dialects-and-compilers.md) for built-in dialects, CIR, and ML compiler ecosystems. - [Testing, tools, and resources](references/testing-tools-and-resources.md) for `mlir-opt`, translation, verification, and upstream references. Use current dialect definitions and verifier contracts as authority. Test transformations at the narrowest textual or executable boundary that proves legality and semantics.
