[GitHub] [tvm] Lunderberg opened a new issue, #12261: [Tracking Issue] Padded Layout Transformations

Lunderberg opened a new issue, #12261:
URL: https://github.com/apache/tvm/issues/12261

   
   ### This issue is to track progress for [padded layout transformations](https://github.com/apache/tvm-rfcs/pull/77)
   
   - [ ] New TIR Op, `tir::builtin::assume`
   - [ ] New lowering transform, remove `tir::builtin::assume`
   - [ ] New TIR Op, `tir::builtin::undef`
   - [ ] New lowering transform, remove `tir::builting::undef`
   - [ ] Enhancements to `transform_layout`
     - [ ] `tir.schedule.transform_layout`, rewrite loop structure if possible, mimicking TE functionality.
     - [ ] Insert pad value into generated TIR, using `tir::if_then_else`, `builtin::assume`, and `builtin::undef`
   - [ ] New utility, reorder loops according to buffer layout
   
     Should be implemented as wrapper function around `Schedule.transform_block_layout`.
   
   - [ ] Enhancement, DomainTouched
   
     Must track a predicate for which this touch occurs, and any known values for this touch.
   
   - [ ] Enhancement, Remove No Op
   
     Should identify writes that are later overwritten or deallocated without affecting the observable outputs.
   
   - [ ] Enhancement, Simplify
   
     Should remove conditional statements that are provable using known contents of a buffer.
   
   - [x] New transform, Hoist Expression. (#11592)
   
   - [ ] New primitive, remove branching through overcompute
   
   - [ ] New primitive, remove overcompute through branching
