Field Detail

TYPE

public static final org.graalvm.compiler.graph.NodeClass<StackValueNode> TYPE

size

protected final int size

slotIdentity

protected final StackValueNode.StackSlotIdentity slotIdentity

All nodes with the same identity get the same stack slot assigned.

stackSlotHolder

protected StackValueNode.StackSlotHolder stackSlotHolder

We need to make sure that the stack block is reserved only once, even when compiler optimizations such as loop unrolling duplicate the actual StackValueNode. While the node itself is cloned, this holder object is not cloned (it is a shallow object copy). The holders are created by the StackValuePhase.

Constructor Detail

StackValueNode

public StackValueNode(long numElements,
                      long elementSize,
                      StackValueNode.StackSlotIdentity slotIdentity)

Method Detail

generate

public void generate(org.graalvm.compiler.nodes.spi.NodeLIRBuilderTool gen)

Specified by:

generate in interface org.graalvm.compiler.nodes.spi.LIRLowerable

stackValue

public static org.graalvm.word.WordBase stackValue(long numElements,
                                                   long elementSize,
