Description

It's quite common to not be focused when coding and mistakenly pass the original arrays to compile instead of the converted ConcreteRArrays, which leads to no MLIR code and the result being hardcoded in the Thunk.

I think it would be a good idea to at least warn the user that no ConcreteRArray was detected when linearizing or that no MLIR code has been emitted.

Contributor guide

Research direction
Examine the linearization and compilation steps to identify where a warning should be added when no MLIR code is emitted. Focus on the conversion from arrays to ConcreteRArray and the Thunk execution.
