    • [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.

    • [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
      - ir_functor_ext.h -> tir/expr_functor.h, tir/stmt_functor.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
      
      * rename big->large

    • [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
