    • [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.
      
      * Remove legacy VarExpr and ExprHash/Equal

    • [REFACTOR][IR] Introduce SeqStmt to replace ir::Block (#4627) · 3595cbe0
      * [REFACTOR][IR] Introduce SeqStmt to replace Block
      
      ir::Block was used to represent a sequence of Stmts in the original low-level IR.
      The nested ir::Block structure is not really friendly for recursive visits,
      especially when the statements are unrolled.
      
      This PR introduce a SeqStmt that directly stores a sequence of statements in an Array container.
      The new SeqStmt will be used as a replacement of the original Block structure.
      
      * [REFACTOR] Migrate use of Block to SeqStmt.

    • [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.

    • [REFACTOR] TVM_REGISTER_API -> TVM_REGISTER_GLOBAL (#4621) · 81523604
      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][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.
