Constructor Detail

FloatConvertNode

public FloatConvertNode(FloatConvert op,
                        ValueNode input)

Method Detail

create

public static ValueNode create(FloatConvert op,
                               ValueNode input)

getFloatConvert

public FloatConvert getFloatConvert()

convert

public Constant convert(Constant c,
                        ConstantReflectionProvider constantReflection)

Specified by:

convert in interface ConvertNode

reverse

public Constant reverse(Constant c,
                        ConstantReflectionProvider constantReflection)

Specified by:

reverse in interface ConvertNode

isLossless

public boolean isLossless()

Description copied from interface: ConvertNode

Check whether a conversion is lossless.

Specified by:

isLossless in interface ConvertNode

Returns:

true iff reverse(convert(c)) == c for all c

canonical

public ValueNode canonical(CanonicalizerTool tool,
                           ValueNode forValue)

Description copied from interface: Canonicalizable.Unary

Similar to Canonicalizable.canonical(CanonicalizerTool), except that implementations should act as if the current input of the node was the given one, i.e., they should never look at the inputs via the this pointer.

Specified by:

canonical in interface Canonicalizable.Unary<ValueNode>

Overrides:

canonical in class UnaryArithmeticNode<ArithmeticOpTable.FloatConvertOp>

lower

public void lower(LoweringTool tool)

Description copied from interface: Lowerable

Expand this node into lower level nodes expressing the same semantics. If the introduced nodes are themselves lowerable, they should be recursively lowered as part of this call.

Specified by:

lower in interface Lowerable

generate

public void generate(NodeValueMap nodeValueMap,
                     ArithmeticLIRGenerator gen)

Specified by:

generate in interface ArithmeticLIRLowerable
