Over the past year, many improvements have been made to the infrastructure for using non-attribute properties in MLIR. Such properties allow constants and other data to be stored inline in the operation struct without potentially-expensive attribute uniquing. This presentation will showcase these improvements, such as new support for such properties in TableGen-based builder/parser/printer generation, operation verification, improved generic builders, and declarative rewrite rules. It will also present future directions for non-attribute properties.
