    • [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.
      
      - lowered_func.h,buffer.h,data_layout.h -> tir/buffer.h,tir/data_layout.h,tir/lowered_func.h
      - ir.h -> tir/expr.h, tir/stmt.h

    • [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] Remove UIntImm to use IntImm

    • [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][DTYPE] Isolate dtype to runtime (#4560) · 7fa8aab5
      dtype.h -> runtime/data_type.h
      
      Changes:
      - Rename all old reference of tvm::Type to DataType
      - ExprNode.type -> ExprNode.dtype
      - Expr.type() -> Expr.dtype()
      - Change Expr related functions to expr_operator.
        - DataType::min() -> min_value(DataType)
        - DataType::max() -> max_value(DataType)
      - Move type constructor Int, UInt, Float, Handle, Bool into DataType.
        - Int(bits) -> DataType::Int(bits)
        - UInt(bits) -> DataType::UInt(bits)

    • [NODE][REFACTOR] Refactor reflection system in node. (#4189) · 78ca6fc8
      * [NODE][REFACTOR] Refactor reflection system in node.
      
      - Removed the old Node, Node is now just an alias of runtime::Object
      - Introduce ReflectionVTable, a new columnar dispatcher to support reflection
        - This allows us to remove vtable from most node objects
        - The VisitAttrs are registered via TVM_RESGITER_NODE_TYPE,
          they are no longer virtual.
      - Consolidated serialization and reflection features into node.
      
      * Explicit type qualification when calling destructor.
      
      * Fix SPIRV, more comments
