Transforming linalg with multiple generic operations about iree-llvm-sandbox HOT 4 CLOSED

You could name the op directly with an attribute and have your transformations hook on to that.

In the rewrite system going forward, we're going to move away from relying on attributes and hooking on to them. Instead, you would want your transformation to return handles to the two generic ops and then directly apply additional (potentially different) transformations on those two handles.

Hi @Mogball ,
Thanks for the answer. Just to understand, let's say I want to flatten the element-wise operation and tile the matmul, how do I do this without naming the operation? Is it through a pattern matching system?

Transformations on operations do not have to be through the pattern rewrite system. You can write a pass and do whatever mutations you want, however you want. But the pattern rewrite system provides structure and reusability. If you can write a pattern to match only the element-wise op and another one that only matches the matmul, then you can use patterns.

This is the feature that @nicolasvasilache added in the latest commits, so I am closing this issue. Thanks!
