[quote="grwlf, post:28, topic:1721, full:true"]
Let me stress the attention on the fact, that MLIR doesn’t only offer different IR, it also
offers different approach to scheduling via its Polyhedral dialect. For example, I see affine
transformations as types in the standard.

This is what I meant in my post

1. MLIR seems to (natively?) support descriptions targeted for polyhedral dialects. Since
TVM does not use the polyhedral model, I guess we would be limited in the usage of this information
but could it also be an impairment?

Since the loop transformations which TVM does are a subset of all possible with the polyhedral
modelling, I guess we would be ok.
Obviously, TVM could offload part of scheduling to MLIR and invoque from there the polyhedral
That I think is part of the goal of MLIR that the "right" dialect is used for the right part
of the whole compilation task
