      * [REFACTOR] Establish printer in the source folder.
      
      As we move towards the unified IR, we will eventually want to build a unified
      printers for both relay and TIR.
      
      This PR isolate the printer component into a separate folder in src as a first step.
      
      - Refactored the Doc DSL using Object, clean up APIs.
      - Isolate out the meta data into a header.
      - move printer into relay_text_printer, add comments about further TODos.
      
      * Rename NodePrinter -> ReprPrinter to distinguish it from other printers

      Spread the arithmetic.h into several components and move
      into arith subfolder.
      
      The arith namespace will be used for arithmetic expression

    • [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)
      
      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.
      
      * Remove legacy VarExpr and ExprHash/Equal

      * [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.

    • [NODE][REFACTOR] Rename IRFunctor->NodeFunctor, use func pointer (#4247) · 9a3d2ec9
      * [NODE][REFACTOR] Rename IRFunctor->NodeFunctor, use function pointer for dispatching.
      
      Previously we used std::function for the functor dispatching.
      It introduces additional overhead and problems during dll destruction(of std::function).
      
      This PR changes the std::function to function pointers.
      This change a bit restrictions around the set_dispatch that we can get around,
      but will improve the general efficiency by reducing one level of indirection in the std::function.
      We also no longer need special marcos to register functions to the Functor.

    • [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.
