Member Data Documentation

◆ _type_key

constexpr const char* tvm::te::TransformNode::_type_key = "Transform"

staticconstexpr

◆ forward_transformation

IndexMap tvm::te::TransformNode::forward_transformation

Map from the original variables to the transformed variables.

Used to determine iterator ranges over the transformed variables.

◆ inverse_transformation

IndexMap tvm::te::TransformNode::inverse_transformation

Map from transformed variables to the original variables.

Used to rewrite expressions containing the original loop iterators in terms of the transformed loop iterators.

◆ original_variables

Array<IterVar> tvm::te::TransformNode::original_variables

The loop variables that were replaced by the transformation.

Prior to applying a layout transformation, these represent the loops to iterate over a tensor as it is being computed, following a row-major traversal of the tensor's original shape in the compute definition.

◆ transformed_variables

Array<IterVar> tvm::te::TransformNode::transformed_variables

The variables generated by the transformation.

After to applying a layout transformation, these represent the loops to iterate over a tensor as it is being computed, following a row-major traversal of the transformed shape of the tensor.

The documentation for this class was generated from the following file:
