Class LIRFrameState

java.lang.Object

com.oracle.graal.lir.LIRFrameState

public class LIRFrameState
extends Object

This class represents garbage collection and deoptimization information attached to a LIR instruction.

Field Summary

Fields

Modifier and Type	Field and Description
protected DebugInfo	debugInfo

private IndexedValueMap	liveBasePointers
protected static EnumSet<LIRInstruction.OperandFlag>	STATE_FLAGS We filter out constant and illegal values ourself before calling the procedure, so LIRInstruction.OperandFlag.CONST and LIRInstruction.OperandFlag.ILLEGAL need not be set.

Field Detail

topFrame

public final BytecodeFrame topFrame

virtualObjects

private final VirtualObject[] virtualObjects

exceptionEdge

public final LabelRef exceptionEdge

debugInfo

protected DebugInfo debugInfo

liveBasePointers

private IndexedValueMap liveBasePointers

STATE_FLAGS

protected static final EnumSet<LIRInstruction.OperandFlag> STATE_FLAGS

We filter out constant and illegal values ourself before calling the procedure, so LIRInstruction.OperandFlag.CONST and LIRInstruction.OperandFlag.ILLEGAL need not be set.
