    • [RUNTIME][OBJECT] Introduce static slots for common objects. (#5423) · 3cc49719
      The _type_child_slots can be used to enable quick type checking optimization
      by checking the whether the type index is within the bound.
      
      This PR enables these static slots:
      
      - Introduce a static assert to avoid the scenario when a developer forget to
        _type_child_slots when the field is set for the type's parent.
      - Revamp and assign static type index to common runtime objects
      - Add a DumpTypeTable call to allow developer monitor the current situation
        of type table and offers suggestions for the slots(ideally the slots equals
        the number of children so there is no overflow.

    • [REFACTOR][IR] Unify IntImm and UIntImm (#4706) · ce807fe8
      * [REFACTOR][IR] Unify IntImm and UIntImm
      
      This PR unifies UIntImm and IntImm to simplify the codebase.
      Unsigned integer constants will also be stored as IntImm.
      
      For uint constant that does not fit into int64(rare case), we introduced
      an intrinsic tvm_big_uint_imm to construct such intgers by its
      lower and higher 32bits.

    • [REFACTOR][IR] tvm::Expr -> PrimExpr(Primitive Expr) (#4669) · d6a23cf5
      * [REFACTOR][IR] tvm::Expr -> PrimExpr(Primitive Expr)
      
      As part of unified IR, we will need to unify relay::Expr
      and the current tvm::Expr under the same base type.
      
      From the techinical point of view. tvm::Expr is a "primitive"
      expression that only contains POD types and handles and does
      not do life-cycle management.
      
      This PR renames Expr->PrimExpr to clarify that.
      We will send a subsequent PR to introduce the base expr class.

      * [REFACTOR][OBJECT] Consoldiate NodePtr/Ref/Hash/Equal and macros to Object.
      
      Historically, we have classes like NodePtr/Ref/HashEqual.
      After unified object protocol, these names are just alias of the object counterpart.
      Moreover, there are helper macros defined over the places for defining these object.
      
      This PR consoldiate the terminologies into the corresponding ones
      in the Object system so we have a clean and consistent API moving forward.

      - 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.

    • [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.
