MLIR allows defining IR for structured control flow and structured MLIR allows defining IR for structured control flow and structured
data types. We choose to take advantage of these properties for the data types. We choose to take advantage of these properties for the
reasons described above. reasons described above.
In particular, the `MemRefType` represents dense non-contiguous memory regions. In particular, the `MemRefType` represents dense non-contiguous memory regions.
This structure should extend beyond simple dense data types and generalize to This structure should extend beyond simple dense data types and generalize to

For such more advanced data types, the control-flow required to traverse the For such more advanced data types, the control-flow required to traverse the
data structures, termination conditions, etc are much less simple to analyze and data structures, termination conditions, etc are much less simple to analyze and
characterize statically. As a consequence we need to also design solutions that characterize statically. As a consequence we need to also design solutions that
stand a chance of evolving into runtime-adaptive computations (e.g. stand a chance of evolving into runtime-adaptive computations (e.g.
