Allows better pack-unpack propagation by first generalizing linalg named ops. This is mainly due to limited support for named ops in layout propagation patterns.
Adds a custom wrapper around Linalg named ops generalization. The custom pattern exposes control over which ops should be generalized. By default, the pass filters out linalg.fill ops as layout propagation and fusion behave better when the named version is present. This improves overall IR quality after bufferization.

Most important generalization is now covered by the added folding patterns. Technically, this further named ops generalization opens up more fusion opportunities when named ops are present. For now keeping it as a draft for further investigation. |
