protected void generateArrayCopy(NodeLIRBuilderTool gen)

getLocationIdentity

public org.graalvm.word.LocationIdentity getLocationIdentity()

TruffleStrings is using the same stub generated by this node to read from byte[]/char[]/int[] arrays and native buffers, so we have to use LocationIdentity.any() here.

Returns:

the identities of all locations killed by this node.

getLastLocationAccess

public MemoryKill getLastLocationAccess()

Specified by:

getLastLocationAccess in interface MemoryAccess

Returns:

a MemoryKill that represents the last memory state in the memory graph for the LocationIdentity returned by MemoryAccess.getLocationIdentity()

setLastLocationAccess

public void setLastLocationAccess(MemoryKill lla)
