Implementations of this method can provide local optimizations like constant folding and
strength reduction.

their stamp if their inputs change. |

virtualize(VirtualizerTool tool)
A node class can implement this method to convey information about what its effect would be
if some of its inputs were virtualized.

it to ValueNode.updateStamp(Stamp), whose return value can be used as the result of this

Canonicalizablenull 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.canonical in interface Canonicalizabletool - provides access to runtime interfaces like MetaAccessProviderprivate static ValueNode tryConstantFold(ValueNode array, ValueNode index, MetaAccessProvider metaAccess, ConstantReflectionProvider constantReflection)
