    • [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] 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] Remove Block
      
      * Add more comments per yizhi's comment

      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)
