Method Detail

instance

public static HostedConfiguration instance()

setDefaultIfEmpty

public static void setDefaultIfEmpty()

createObjectLayout

public static ObjectLayout createObjectLayout()

createObjectLayout

public static ObjectLayout createObjectLayout(jdk.vm.ci.meta.JavaKind referenceKind)

Defines the layout of objects. The layout of instance objects is:

• hub (reference)
• instance fields (references, primitives)
• optional: identity hashcode (int)

The hashcode is appended after instance fields and is only present if the identity hashcode is used for that type. The layout of array objects is:

• hub (reference)
• array length (int)
• identity hashcode (int)
• array elements (length * reference or primitive)

The hashcode is always present in arrays. Note that on 64-bit targets it does not impose any size overhead for arrays with 64-bit aligned elements (e.g. arrays of objects).

createHostVM

public SVMHost createHostVM(org.graalvm.compiler.options.OptionValues options,
                            ClassLoader classLoader,
                            ClassInitializationSupport classInitializationSupport,

                                       FeatureHandler featureHandler,

collectMonitorFieldInfo

public void collectMonitorFieldInfo(com.oracle.graal.pointsto.BigBang bb,
                                    HostedUniverse hUniverse,

processedSynchronizedTypes

protected void processedSynchronizedTypes(com.oracle.graal.pointsto.BigBang bb,
                                          HostedUniverse hUniverse,
                                          Set<com.oracle.graal.pointsto.meta.AnalysisType> immutableTypes)

Process the types that the analysis found as needing synchronization.

maybeSetMonitorField

protected static void maybeSetMonitorField(HostedUniverse hUniverse,
                                           Set<com.oracle.graal.pointsto.meta.AnalysisType> immutableTypes,
                                           com.oracle.graal.pointsto.meta.AnalysisType type)

Monitor fields on arrays would increase the array header too much. Also, types that must be immutable cannot have a monitor field.
