Direct Known Subclasses:

AArch64TruffleCallBoundaryInstumentationFactory, AMD64TruffleCallBoundaryInstrumentationFactory

public abstract class TruffleCallBoundaryInstrumentationFactory
extends Object

A service for creating a specialized CompilationResultBuilder used to inject code into the beginning of a call boundary method. The injected code tests the entryPoint field of the installedCode field of the receiver and tail calls it if it is non-zero:

 long ep = this.installedCode.entryPoint;
 // post-volatile-read barrier
 if (ep != null) {
     tailcall(ep);
 }
 // normal compiled code
