Detailed Description

Builds the dataflow of one block from expressions.

Every operation writes its result to a new transient scalar, so values combine freely, e.g. store(op(fp_mul, {read("x", {i}), constant(2.0, Double)}, Double), "y", {i}).

◆ read() [1/2]

KernelValue sdfg::fp_math::BlockBuilder::read	(	const std::string &	container,
		const data_flow::Subset &	subset = {} )

Reads a scalar container, or the element at subset of a pointer container.

◆ read() [2/2]

KernelValue sdfg::fp_math::BlockBuilder::read	(	data_flow::AccessNode &	node,
		const data_flow::Subset &	subset,
		const types::IType &	base_type )

Reads node at subset through a memlet of base_type.

◆ store() [1/2]

void sdfg::fp_math::BlockBuilder::store	(	const KernelValue &	value,
		const std::string &	container,
		const data_flow::Subset &	subset = {} )

Assigns value to a scalar container, or to the element at subset of a pointer container.

◆ store() [2/2]

void sdfg::fp_math::BlockBuilder::store	(	const KernelValue &	value,
		data_flow::AccessNode &	node,
		const data_flow::Subset &	subset,
		const types::IType &	base_type )

Assigns value, converted to the target's element type, to node at subset.
