tqchen opened a new pull request #5271: [RUNTIME] Introduce RValue reference(move) support to TypedPackedFunc URL: https://github.com/apache/incubator-tvm/pull/5271 This PR introduces RValue reference support the PackedFunc calling convention to address the above issue. Specifically, when an argument is a r-value reference, we will use a assign a different type code(`kObjectRValueRefArg`), and pass `Object**` (the address to the Object pointer) instead through the values array. The callee can choose to move out this Object pointer and set the original Object pointer from the caller side to be nullptr. We also add move support to the python side. This enhancement will enable copy on write optimizations through out the TVM stack.
