Example 1 with OrderedWriteNode

use of org.graalvm.compiler.nodes.memory.OrderedWriteNode in project graal by oracle.

the class DefaultJavaLoweringProvider method lowerStoreFieldNode.

protected void lowerStoreFieldNode(StoreFieldNode storeField, LoweringTool tool) {
    StructuredGraph graph = storeField.graph();
    ResolvedJavaField field = storeField.field();
    ValueNode object = storeField.isStatic() ? staticFieldBase(graph, field) : storeField.object();

    ValueNode value = implicitStoreConvert(graph, getStorageKind(storeField.field()), storeField.value());
    AddressNode address = createFieldAddress(graph, object, field);
    assert address != null;
    BarrierType barrierType = barrierSet.fieldStoreBarrierType(field, getStorageKind(field));
    WriteNode memoryWrite;
    if (storeField.ordersMemoryAccesses()) {
        memoryWrite = graph.add(new OrderedWriteNode(address, fieldLocationIdentity(field), value, barrierType, storeField.getMemoryOrder()));
