Member Function Documentation

◆ buildNewModule()

FModuleOp LowerLayersPass::buildNewModule	(	OpBuilder &	builder,
		LayerBlockOp	layerBlock,
		SmallVectorImpl< PortInfo > &	ports
	)

private

Safely build a new module with a given namehint.

Multi-process safe function to build a module in the circuit and return it.

This handles geting a lock to modify the top-level circuit.

The name provided is only a namehint for the module—a unique name will be generated if there are conflicts with the namehint in the circuit-level namespace.
