tvm::script::ir_builder::IRBuilderNode Class Reference

A dialect-agnostic IRBuilder that constructs any IR of TVM. An idiomatic use of this class is to put this inside the RAII with-scope, call dialect-specific methods accordingly. Upon exiting the scope. More...

Detailed Description

A dialect-agnostic IRBuilder that constructs any IR of TVM. An idiomatic use of this class is to put this inside the RAII with-scope, call dialect-specific methods accordingly. Upon exiting the scope.

  using tvm::script::ir_builder::IRBuilder;
  using T = tvm::script::ir_builder::tir;
  IRBuilder builder;
  // Step 1. Place IRBuilder inside the with-scope.
  {
    With<IRBuilder> _(builder);
    // Step 2. Call dialect-specific methods.
    With<T::PrimFuncFrame> _2(...);
    T::MatchBuffer(...);
  }
  // Step 3. Return the constructed PrimFunc.
  return builder->Get<PrimFunc>();

FindFrame()

template<typename TFrame >

Optional< TFrame > tvm::script::ir_builder::IRBuilderNode::FindFrame

inline

Find a frame of the given type in the stack this->frames from top to bottom.

Template Parameters

T	The type of the frame to find.

Returns

The frame if found, otherwise std::nullopt.

Examples

/workspace/include/tvm/script/ir_builder/base.h.

Get()

template<typename TObjectRef >

TObjectRef tvm::script::ir_builder::IRBuilderNode::Get

inline

Get the IR being constructed.

Template Parameters

TObjectRef

The type of the IR being constructed.

Returns

The resulting IR. Throw an exception if the IR is not constructed yet.

Examples

/workspace/include/tvm/script/ir_builder/base.h.

GetLastFrame()

template<typename TFrame >

Optional< TFrame > tvm::script::ir_builder::IRBuilderNode::GetLastFrame

inline

Get the frame on top of the stack this->frames if its type is TFrame.

Template Parameters

TFrame

The assumed type of the last frame on stack.

Returns

The frame if the stack is non-empty and the top of the stack is of type TFrame. Otherwise std::nullopt.

Examples

/workspace/include/tvm/script/ir_builder/base.h.
