Method Detail

addBarriers

void addBarriers(FixedAccessNode n)

fieldLoadBarrierType

OnHeapMemoryAccess.BarrierType fieldLoadBarrierType(ResolvedJavaField field,
                                                    JavaKind storageKind)

fieldStoreBarrierType

OnHeapMemoryAccess.BarrierType fieldStoreBarrierType(ResolvedJavaField field,
                                                     JavaKind storageKind)

readBarrierType

OnHeapMemoryAccess.BarrierType readBarrierType(RawLoadNode load)

storeBarrierType

OnHeapMemoryAccess.BarrierType storeBarrierType(RawStoreNode store)

arrayStoreBarrierType

OnHeapMemoryAccess.BarrierType arrayStoreBarrierType(JavaKind storageKind)

guessStoreBarrierType

OnHeapMemoryAccess.BarrierType guessStoreBarrierType(ValueNode object,
                                                     ValueNode value)

mayNeedPreWriteBarrier

boolean mayNeedPreWriteBarrier(JavaKind storageKind)

Determine whether writes of the given storageKind may ever need a pre-write barrier.

Returns:

false if no writes of storageKind ever need a pre-write barrier; true if writes of storageKind may need a pre-write barrier at least under certain circumstances.
