Method Detail

canonical

public Node canonical(CanonicalizerTool tool)

Description copied from interface: Canonicalizable

Implementations of this method can provide local optimizations like constant folding and strength reduction. Implementations should look at the properties and inputs of the current node and determine if there is a more optimal and always semantically correct replacement.
The return value determines the effect that the canonicalization will have:

• Returning an pre-existing node will replace the current node with the given one.
• Returning a newly created node (that was not yet added to the graph) will replace the current node with the given one, after adding it to the graph. If both the replacement and the replacee are anchored in control flow (fixed nodes), the replacement will be added to the control flow. It is invalid to replace a non-fixed node with a newly created fixed node (because its placement in the control flow cannot be determined without scheduling).
• Returning null will delete the current node and replace it with null at all usages. Note that it is not necessary to delete floating nodes that have no more usages this way - they will be deleted automatically.

Specified by:

canonical in interface Canonicalizable

Parameters:

tool - provides access to runtime interfaces like MetaAccessProvider

lower

public void lower(LoweringTool tool)

Description copied from interface: Lowerable

Expand this node into lower level nodes expressing the same semantics. If the introduced nodes are themselves lowerable, they should be recursively lowered as part of this call.

lower in interface Lowerable

lower in interface MacroInvokable
