Oh you should definitely watch the recording (or skim through) Open MLIR Meeting 2/23/2023: MLIR Actions: Tracing and Debugging MLIR-based Compilers - #2 by mehdi_amini
I have some cool demo there!
The doc: Action: Tracing and Debugging MLIR-based Compilers - MLIR
We should add more Actions to the codebase also (hook in the transformation dialect?)!
I think right now --log-actions-to wouldn’t be enough because it won’t print the IR after conversion, only before.
