    • [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] Automatically deduce function type signature in Registry.set_body_typed (#4623) · d5d63a44
      Previously we support a limited case of function type deduction and in many places
      we have to supply the type twice during set_body_typed (one in the template parameter, another in the lambda signature).
      
      This PR improves the deduce function by enablng automatic function signature deduction.
      
      ```
      TVM_REGISTER_GLOBAL("sub")
      .set_body_typed([](int x, int y) -> int { return x - y; });
      ```
      
      Unfortunately, because of template conflict, we can not support the original case
      where both type signature and lambda are supplied through set_body_typed.
      
      This PR refactors the existing regsitration to the new style.

      TVM_REGSISTER_API is an alias of TVM_REGISTER_GLOBAL.
      In the spirit of simplify redirections, this PR removes
      the original TVM_REGISTER_API macro and directly use TVM_REGISTER_GLOBAL.
      
      This type of refactor will also simplify the IDE navigation tools
      such as FFI navigator to provide better code reading experiences.

    • [REFACTOR] Unified IR base types. (#4616) · 1ecd3ee2
      This PR moves a few base types from relay to the ir sub-folder.
      These types will serve as a common type system across the stack.
      
      Notably, we want to be able to use the same FuncType for all function signatures.
      I tried to make a minimum move to bring the necessary dependencies for a FuncType.
      We can discuss what additional things we want to move as a follow-up.
      
      Notably, because the TensorType will have a dependency on low-level Expr,
      we will need to break the type.h into two files and introduce a
      tensor_type.h(or leave them in relay for now).

    • [REFACTOR][TYPE] Remove un-necessary var sub-field in GlobalTypeVar and TypeVar (#4615) · 24e6fcb6
      Currently, we use a tvm::Var to represent a placeholder for shapes in generic types.
      This is not necessary for GlobalTypeVar(as we never parameterize by shape var),
      and is a bit twisted for TypeVar.
      
      As we move to a unified type system, we want to break the dependency
      from the base TypeVar(which is shared across the languages) from the expression.
      Note that it is fine for TensorType to depend on Expr.
      
      One alternative solution to embed the Var would be to introduce a TypeVarExpr,
      which can wrap a TypeVar as Expr. However, this new alternative won't be
      natural until we migrate the type to the global scope.
      
      Lucikly, we have not yet start to depend on the shape parameterization heavily yet.
      
      This PR removes the tvm::Var from the typevars. We will follow up with another
      PR to migrate the types to a base location. After that, we should be able to
      use the more elegant approach via TypeVarExpr.

    • [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.

    • [Relay][Hashing] Structural hash - incorporate the var type into its hash (#3267) · 1f4ec9e2
      Currently, the BindVar function does not take Var type into account. This causes
      two same graph structures with different var shapes to have same hash.
      Structural hash is used for keeping track of which operators we have
      already compiled. Because of this, two operators with different shapes end up
      pointing to same compiled code. The failure is encountered at runtime, where the
      expected input shape asserts are not met.
