    • [TIR][TARGET] Refactor Target codegen to use IRModule and PrimFunc. (#5107) · 841725cc
      As part of the unified IR refactor.
      This PR refactors the target codegen to use IRModule containing tir::PrimFuncs.
      
      In order to break the refactor into several steps without breaking the codebase,
      we built an conversion pass to convert Array<LoweredFunc> into IRModule.
      
      The follow-up refactors will gradually move the passes covered by IRModule up
      until we cover all the passes. Then we can remove the additional redundant
      concepts such as LoweredFunc.

      TIR is the new namespace for low-level IR
      for tensor-level optimizations and loop transformations.
      
      This PR establishes the namespace and files.
      
      - lowered_func.h,buffer.h,data_layout.h -> tir/buffer.h,tir/data_layout.h,tir/lowered_func.h

    • [REFACTOR] top - namespace for Tensor Operation DSL (#4727) · b8261426
      * [REFACTOR] introduce top - Tensor Operation DSL.
      
      Historically we put Tensor, Schedule and compute under the root tvm namespace.
      This is no longer a good idea as the project's scope grows larger
      than the tensor operation DSL.
      
      This PR introduces top -- a namespace for tensor operational
      DSL concepts such as schedule, tensor, compute.
      We moved the related files to the new top subfolder.
      
      * Move relevant files into include/tvm/top and src/top

    • [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][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.

    • [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.
