| An analysis and IR rewriting pass that analyzes allocations and deallocations of input | ||
| IR and generates a new IR where all allocations are turned to memref.subviews of a | ||
| statically-allocated memref. The subviews take care of the liveness of buffers and | ||
| at the same time exploits reuse of memory as much as possible. |

Hi @javedabsar1 and @matthias-springer , Sharing this draft PR as a small first upstream step for the Static Memory Planner direction discussed on Discourse. I scoped it deliberately narrowly:
The idea was to align with the “single function block first” guidance and demonstrate the intended placement and use of existing MLIR infra before attempting broader planner or rewrite work. Would appreciate your thoughts and feedback on this. |
