Member Data Documentation

◆ _type_key

constexpr const char* tvm::te::TensorIntrinNode::_type_key = "TensorIntrin"

staticconstexpr

◆ body

Stmt tvm::te::TensorIntrinNode::body

The normal statement to execute the intrinsic.

◆ buffers

Array<Buffer> tvm::te::TensorIntrinNode::buffers

Symbolic buffers of each output/input tensor buffers[0:len(inputs)] are buffers of the inputs. buffers[len(inputs):] are buffers of each output.

Note: When a field in Buffer is Var, it means we can be flexible wrt that field and Var can occur in body. When it is a constant, it means we can only take data in that shape.

◆ inputs

Array<Tensor> tvm::te::TensorIntrinNode::inputs

List of inputs of operator, placeholder in postdfs order.

◆ name

std::string tvm::te::TensorIntrinNode::name

The name of the intrinsic.

◆ op

Operation tvm::te::TensorIntrinNode::op

The operation this intrinsics is carrying out.

◆ reduce_init

Stmt tvm::te::TensorIntrinNode::reduce_init

Special statement for reduction op, can be None reset the value of output buffer to identity value.

◆ reduce_update

Stmt tvm::te::TensorIntrinNode::reduce_update

Special statement for reduction op, can be None Reduce: do a reduction of current output buffer with the result.

◆ scalar_params

Array<Var> tvm::te::TensorIntrinNode::scalar_params

List of scalar variables, used in body. These placeholders will be bound to expressions passed in when the TensorIntrin is called from a TensorComputeOp.
