    • [REFACTOR][CODEGEN] codegen->target, build_module->driver (#4742) · 33b0831c
      This PR moves the codegen related code into the target folder,
      as they are target specific functionalities.
      
      We also adopt the term "compiler driver" in common compiler infra
      such as rust, GHC and clang.
      As a result, build_module is moved into the driver folder.

    • [REFACTOR] Establish tir (#4740) · cf59b206
      TIR is the new namespace for low-level IR
      for tensor-level optimizations and loop transformations.
      
      This PR establishes the namespace and files.

    • [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] Allow Module to store BaseFunc. (#4678) · 3d52a99c
      Under the unified IR. We will allow a single IRModule
      to store different function variants, such as relay::Function,
      ExternFunc, and low-level function.
      
      This PR changes relay::Function -> BaseFunc in the module file
      to support multiple function variants.

    • [REFACTOR][IR] Initialize Unified IR Expr Data Structure (#4673) · 12e51e6c
      This PR moves a few base types from relay and low-level Expr into the ir sub-folder.
      These classes will serve as a common type system across the stack.
      
      Rationale:
      
      - PrimExpr for low-level expressions
      - RelayExpr for advanced features, including Function definition.
      - Introduce BaseFunc to host all functions, including future PrimFunc(low-level expr functions, subject to discussion).
      
      This is a minimum change we can do to unify the classes into a common hierarchy.
      The main data structure that are variant specific will still be kept in the sub-namespaces.
      We only include classes that is needed to allow a common Module class.
      - BaseFunc
      - GlobalVar
      - Type definition part of ADT
      
      We will only need the BaseFunc and their checked_type to decide the calling convention
      across the function variants.

    • [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.
      
      Move EnvFunc's definition to node.

    • [REFACTOR][OBJECT] Consoldiate NodePtr/Ref/Hash/Equal to Object (#4603) · a8c36921
      * [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.

    • [RFC][RUNTIME] Introduce new object protocol. (#4115) · a0bd3786
      * [RUNTIME] Introduce new object protocol.
      
      This PR introduces a new object protocol to unify the node and object.
      We also updated the existing runtime::vm code to make use of the new system.
      
      Update to the node will be done in a follow up PR.
      
      Other changes:
      
      - Remove object related code in json serializer as that code logic was not complete
        and we have a separate serializer for VM, can revisit later.
      
      * address review  comment
