URL: https://github.com/apache/incubator-tvm/pull/5898#issuecomment-648223645


   There are very simple unit tests for `LegalizeInvalidAttach`
   
   ```python
   import tvm
   from tvm import te
   
   A = te.compute((10, 10), lambda i, j: 1.0, name='A')
   B = te.compute((10, 10), lambda i, j: A[i][j], name='B')
   
   # Case 1: Split an axis which is the target of a compute_at
   s = te.create_schedule([B.op])
   s[A].compute_at(s[B], B.op.axis[1])
   s[B].split(B.op.axis[1], 2)
   
   print(tvm.lower(s, [A, B], simple_mode=True))
   
   # Case 2: Fuse an axis which is the target of a compute_at
   s = te.create_schedule([B.op])
   s[A].compute_at(s[B], B.op.axis[1])
   s[B].fuse(B.op.axis[0], B.op.axis[1])
   
   print(tvm.lower(s, [A, B], simple_mode=True))
   ```
