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.

◆ lowerInlineLayerBlock()

void LowerLayersPass::lowerInlineLayerBlock	(	LayerOp	layer,
		LayerBlockOp	layerBlock
	)

private

Lower an inline layerblock to an ifdef block.

	)

private

◆ removeLayersFromPorts()

void LowerLayersPass::removeLayersFromPorts ( FModuleLike moduleLike )

Definition at line 227 of file LowerLayers.cpp.

◆ removeLayersFromValue()

void LowerLayersPass::removeLayersFromValue ( Value value )

private

Update the value's type to remove any layers from any probe types.

◆ runOnModuleLike()

FailureOr< InnerRefMap > LowerLayersPass::runOnModuleLike ( FModuleLike moduleLike )

private

Strip layer colors from the module's interface.

Definition at line 272 of file LowerLayers.cpp.

◆ runOnOperation()

void LowerLayersPass::runOnOperation ( )

overrideprivate

Entry point for the function.

Process a circuit to remove all layer blocks in each module and top-level layer definition.
