Detailed Description
This is used to report the reduction patterns for a Dialect.
While using mlir-reduce to reduce a module, we may want to transform certain cases into simpler forms by applying certain rewrite patterns. Implement the populateReductionPatterns to report those patterns by adding them to the RewritePatternSet.
Example: MyDialectReductionPattern::populateReductionPatterns( RewritePatternSet &patterns) { patterns.add<TensorOpReduction>(patterns.getContext()); }
For DRR, mlir-tblgen will generate a helper function populateWithGenerated which has the same signature therefore you can delegate to the helper function as well.
Example: MyDialectReductionPattern::populateReductionPatterns( RewritePatternSet &patterns) { // Include the autogen file somewhere above. populateWithGenerated(patterns); }

Patterns provided here are intended to transform operations from a complex form to a simpler form, without breaking the semantics of the program being reduced.
For example, you may want to replace the tensor<?xindex> with a known rank and type, e.g. tensor<1xi32>, or replacing an operation with a constant.
