saveRegistersOp

protected StandardOp.SaveRegistersOp saveRegistersOp

Constructor Detail

SaveAllRegistersNode

public SaveAllRegistersNode()

Method Detail

generate

public void generate(NodeLIRBuilderTool gen)

Specified by:

generate in interface LIRLowerable

getSaveRegistersOp

public StandardOp.SaveRegistersOp getSaveRegistersOp()

Returns:

the map from registers to the stack locations in they are saved

saveAllRegisters

public static long saveAllRegisters()

Returns:

a token that couples this node to an UncommonTrapCallNode so that the latter has access to the register save map

getLocationIdentity

public LocationIdentity getLocationIdentity()

Description copied from interface: MemoryCheckpoint.Single

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

Specified by:

getLocationIdentity in interface MemoryCheckpoint.Single

Returns:

the identity of the location killed by this node.
