canDeferPlugin

public boolean canDeferPlugin(org.graalvm.compiler.nodes.graphbuilderconf.GeneratedInvocationPlugin plugin)

Fold and Node.NodeIntrinsic can be deferred during parsing/decoding. Only by the end of Snippet instantiation do they need to have been processed. This is how SVM handles snippets. They are parsed with plugins disabled and then encoded and stored in the image. When the snippet is needed at runtime the graph is decoded and the plugins are run during the decoding process. If they aren't handled at this point then they will never be handled.

handleInvokeWithException
