Class FieldsOffsetsFeature

java.lang.Object

com.oracle.svm.graal.hosted.FieldsOffsetsFeature

All Implemented Interfaces:

org.graalvm.nativeimage.hosted.Feature

public class FieldsOffsetsFeature
extends Object
implements org.graalvm.nativeimage.hosted.Feature

Graal uses unsafe memory accesses to access Nodes and LIRInstructions. The offsets for these accesses are maintained in Fields, which are accessible from meta-classes such as NodeClass and LIRInstructionClass. We do not want to replace the whole meta-classes. Instead, we just replace the long[] arrays that hold the actual offsets.
