MLIR — Defining a New Dialect

Table of Contents In the last article in the series, we migrated the passes we had written to use the tablegen code generation framework. That was a preface to using tablegen to define dialects. In this article we’ll define a dialect that represents arithmetic on single-variable polynomials, with coefficients in $\mathbb{Z} / 2^{32} \mathbb{Z}$ (32-bit unsigned integers). The code for this article is in this pull request, and as usual the commits are organized to be read in order.
