nodeRewritingAssumption

private final com.oracle.truffle.api.utilities.CyclicAssumption nodeRewritingAssumption

When this call target is inlined, the inlining InstalledCode registers this assumption. It gets invalidated when a node rewriting is performed. This ensures that all compiled methods that have this call target inlined are properly invalidated.

cloneIndex

private int cloneIndex
