Method Detail

getLocationIdentity

public org.graalvm.word.LocationIdentity getLocationIdentity()

Specified by:

getLocationIdentity in interface MemoryAccess

getKilledLocationIdentities

public org.graalvm.word.LocationIdentity[] getKilledLocationIdentities()

Description copied from interface: MultiMemoryKill

This method is used to determine which set of memory locations is killed by this node. Returning the special value LocationIdentity.any() will kill all memory locations.

Specified by:

getKilledLocationIdentities in interface MultiMemoryKill

Returns:

the identities of all locations killed by this node.

generate

public void generate(NodeLIRBuilderTool gen)

Specified by:

generate in interface LIRLowerable

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 newlla)

Specified by:

setLastLocationAccess in interface MemoryAccess

Parameters:

newlla - the MemoryKill that represents the last kill of the LocationIdentity returned by MemoryAccess.getLocationIdentity()

compress

public static int compress(org.graalvm.word.Pointer src,
                           org.graalvm.word.Pointer dst,
                           int len,
                           JavaKind readKind)
