    • [REFACTOR] Establish printer in the source folder (#4752) · e4d817d4
      * [REFACTOR] Establish printer in the source folder.
      
      As we move towards the unified IR, we will eventually want to build a unified
      printers for both relay and TIR.
      
      This PR isolate the printer component into a separate folder in src as a first step.
      
      - Refactored the Doc DSL using Object, clean up APIs.
      - Isolate out the meta data into a header.
      - move printer into relay_text_printer, add comments about further TODos.
      
      * Rename NodePrinter -> ReprPrinter to distinguish it from other printers

    • [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

    • [REFACTOR][IR] attrs.h -> ir (#4709) · b0b51f25
      This PR moves attrs.h into the ir folder as it
      can serve as a common infra for building ir dats structures.
      
      We also moved common container(FloatImm) into ir/expr.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] Unified IR Primitive Op and Registry (#4687) · d8f06020
      This PR migrates relay's Op into the ir folder.
      Op and its registry provides an useful mechanism to
      store any attribute meta-data of an operator include
      function signatures, lowering rules, side effect etc.
      
      These features are not only useful for Relay, but also needed in the low-level IR.
      At the current moment, intrinsic functions in the low-level IR are simply
      represented by a string. This means we cannot type-check the low-level IR
      when the type does not meet the constraint, nor can we obtain further
      information such as side-effect and read write relation of these intrinsics
      wrt to arguments.
      
      Op will be used as the way to handle primitive ops(in DL terminology)
      (builtin intrinsics or in compiler terminology).
      We will perform follow-up refactors to make low-level CallNode
      take Op as the function argument.

    • [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] Automatically deduce function type signature in Registry.set_body_typed (#4623) · d5d63a44
      Previously we support a limited case of function type deduction and in many places
      we have to supply the type twice during set_body_typed (one in the template parameter, another in the lambda signature).
      
      This PR improves the deduce function by enablng automatic function signature deduction.
      
      ```
      TVM_REGISTER_GLOBAL("sub")
      .set_body_typed([](int x, int y) -> int { return x - y; });
      ```
      
      Unfortunately, because of template conflict, we can not support the original case
      where both type signature and lambda are supplied through set_body_typed.
      
      This PR refactors the existing regsitration to the new style.

    • [REFACTOR] Unified IR base types. (#4616) · 1ecd3ee2
      This PR moves a few base types from relay to the ir sub-folder.
      These types will serve as a common type system across the stack.
      
      Notably, we want to be able to use the same FuncType for all function signatures.
      I tried to make a minimum move to bring the necessary dependencies for a FuncType.
      We can discuss what additional things we want to move as a follow-up.
      
      Notably, because the TensorType will have a dependency on low-level Expr,
      we will need to break the type.h into two files and introduce a
      tensor_type.h(or leave them in relay for now).
