Constructor Detail

CompilationState

public CompilationState(Instruction call,
                        boolean isExtant,
                        OptOptions options,
                        CompiledMethod cm,
                        int realBCI)

Parameters:

call - the call instruction being considered for inlining.

isExtant - is the receiver of a virtual call an extant object?

options - controlling compiler options

cm - compiled method of the IR object being compiled

realBCI - the real bytecode index of the call instruction, not adjusted because of OSR

Method Detail

isInvokeInterface

public boolean isInvokeInterface()

Does this state represent an invokeinterface call?

Returns:

true if it is an interface call or false if it is not.

getInlineDepth

public int getInlineDepth()

Returns:

the depth of inlining so far.

getCallInstruction

public Instruction getCallInstruction()

Returns:

the call instruction being considered for inlining

obtainTarget

public RVMMethod obtainTarget()

Obtains the target method from the compilation state. If a computed target is present, use it.

Returns:

the obtained target

getOptions

public OptOptions getOptions()

Returns:

the controlling compiler options

getIsExtant

public boolean getIsExtant()

Returns:

whether or not the receiving object is extant

getHasPreciseTarget

public boolean getHasPreciseTarget()

Returns:

whether or not the target is precise (ie needs no guard)

getRootMethod

public NormalMethod getRootMethod()

Returns:

the root method of the compilation

getMethod

public NormalMethod getMethod()

Returns:

the method being compiled

getRealBytecodeIndex

public int getRealBytecodeIndex()

Returns:

the real bytecode index associated with this call

getSequence

public InlineSequence getSequence()

Returns:

the inlining sequence

getCompiledMethod

public CompiledMethod getCompiledMethod()

Returns:

the compiled method
