    • [NODE][REFACTOR] Refactor reflection system in node. (#4189) · 78ca6fc8
      * [NODE][REFACTOR] Refactor reflection system in node.
      
      - Removed the old Node, Node is now just an alias of runtime::Object
      - Introduce ReflectionVTable, a new columnar dispatcher to support reflection
        - This allows us to remove vtable from most node objects
        - The VisitAttrs are registered via TVM_RESGITER_NODE_TYPE,
          they are no longer virtual.
      - Consolidated serialization and reflection features into node.
      
      * Explicit type qualification when calling destructor.
      
      * Fix SPIRV, more comments

    • [REFACTOR][NODE][RUNTIME] Move Node to the new Object protocol. (#4161) · 7895adb2
      * [REFACTOR][NODE][RUNTIME] Move Node to the new Object protocol.
      
      This PR removes the original node system, and make node as a subclass of Object.
      This is a major refactor towards a better unified runtime object system.
      
      List of changes in the refactor:
      
      - We now hide data_ field, use Downcast explicitly to get a sub-class object.
      - Removed the node system FFI in python.
      - Removed the node C API, instead use PackedFunc for list and get attrs.
      - Change relay::Op::set_attr_type_key(attr_key_name) to relay::Op::set_attr_type<AttrType>().
        - This change was necessary because of the new Object registration mechanism.
        - Subsequent changes to the op registrations
        - The change revealed a few previous problems that is now fixed.
      - Patched up a few missing node type registration.
        - Now we will raise an error if we register object that is not registered.
      - The original node.h and container.h are kept in the same location.
      - Calling convention: kObjectHandle now equals the old kNodeHandle, kNodeHandle is removed.
      - IRFunctor now dispatches on ObjectRef.
      - Update to the new type checking API: is_type, derived_from are replaced by IsInstance.
      - Removed .hash member function, instead use C++ convention hasher functors.

    • [RUNTIME] Refactor object python FFI to new protocol. (#4128) · 02c1e117
      * [RUNTIME] Refactor object python FFI to new protocol.
      
      This is a pre-req to bring the Node system under object protocol.
      Most of the code reflects the current code in the Node system.
      
      - Use new instead of init so subclass can define their own constructors
      - Allow register via name, besides type idnex
      - Introduce necessary runtime C API functions
      - Refactored Tensor and Datatype to directly use constructor.

    • [RFC][RUNTIME] Introduce new object protocol. (#4115) · a0bd3786
      * [RUNTIME] Introduce new object protocol.
      
      This PR introduces a new object protocol to unify the node and object.
      We also updated the existing runtime::vm code to make use of the new system.
      
      Update to the node will be done in a follow up PR.
      
      Other changes:
      
      - Remove object related code in json serializer as that code logic was not complete
        and we have a separate serializer for VM, can revisit later.
