[Static Runtime] Fix aten::clone out variant (#78297) (#78322)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/78297
Clone followed by expand/expand_as due to memoryOverlap check on copy_ native method. Refer to T118519310 for more details.
Crashing test case:
a = tensor(3,1) // strides = (1,1)
B = tensor(3,2) // strides = (2,1)
Temp = a.expand_as(b). // creates temp with shape as (3,2) and strides as (1,0)
temp.clone() // crashe on copy_ due to memoryOverlap
Fix: Disable the out variant for the expanded tensor.
- Calls native clone instead of out variant for clone dealing with expanded tensors
- Added test case for both clone variants (out and native clones)
- Increased the tensor size for memory planner test case to trigger dynamic allocation
Test Plan:
