That would be up to a vendor to do the release (at least for now) How do we ensure conformance?…

The examples below are not meant to be accurate, and it’s just an idea of what the design is. The actual implementation may end up very different and will be discussed in the respective PRs. Cost model / Target Descriptor Reasonable consensus that we need a generic way to represent multiple targets in MLIR and that cost models…
