Title: Are we fully leveraging TableGen in MLIR?
Speaker: Kshitij Jain
------
Slides: llvm.org/devmtg/2025-10/slides/quick_talks/jain.pdf
-----
While TableGen descriptions in MLIR greatly reduce boilerplate in creating new IR entities (dialects, types, ops etc.), their utility is sometimes underestimated beyond this narrow role. TableGen descriptions, should and can be more. As such, the goal of this talk is to demonstrate why Tablegen descriptions should - and how they can - serve as a single source of truth, for a given IR entity, encoding all information required to effectively interface with said IR entity. Rich TableGen descriptions can: 1) Make a compiler's domain and feature-set clearer. 2) Make a compiler's behavior more apparent and robust. 3) Reduce the mental overhead on compiler developers. 4) Lower the barrier to entry for new contributors. Audience can expect this talk to help them realize the above-mentioned benefits of richer TableGen descriptions through existing utilities, concepts, and often underappreciated software engineering pragmatisms.
