reshape only was a property about the function itself, the property have well-defined meaning in functional land. While alias property itself does not have a clear definition in the function land and is closer to the execution property. So likely a reshape only tag can appear in early stage of compilation without a problem. While alias tag would likely need to only appear when we start to think about memory planning. For general ops, having alias information alone may not give a complete picture, as the operator semantics itself is also part of the picture. For some ops, alias needs to be enforced(e.g. case of scatter sparse add to dense), while others the impact is more minimum(e.g. reshape). Reshape only in that regard is a more narrow tag that specifies the op semantics as well -- This is an automated message from the Apache Git Service.
