@@ -110,6 +110,8 @@ class UOps(HashEnum):
Swizzle inserts a movement op between a UOp and its children. Because movement ops (reshape, expand, shrink, permute, pad) are not allowed in an AST,
the scheduler rewrites SWIZZLE by pushing its ShapeTracker through reduceops or elementwise ops to the edges of the graph.
This movement op can push up to the LOADs and/or down to the STOREs.
Example:
```python
a = Tensor.empty(32, 32)
