Hi all, We are trying to migrate our custom conversion-based bufferization to the one-shot one. In the documentation ( Bufferization - MLIR ), there is a preprocessing step for destination passing style before the bufferization. When migrating to one-shot bufferization, should we handle destination p…

That’s correct. The preprocessing steps are optional. One-Shot Bufferize was designed for ops that are in DPS (destination-passing style). Ops that are not in DPS can still be bufferized, but a new buffer will be allocated for every tensor result. That’s functionally correct but inefficient. I’m no…

Thank you for your confirmation. We will explore the option of handling the bufferization first to see how everything goes on.
