Specified by:

getOp in class UnaryArithmeticNode<ArithmeticOpTable.FloatConvertOp>

getFloatConvert

public FloatConvert getFloatConvert()

convert

public jdk.vm.ci.meta.Constant convert(jdk.vm.ci.meta.Constant c,
                                       jdk.vm.ci.meta.ConstantReflectionProvider constantReflection)

Specified by:

convert in interface ConvertNode

public jdk.vm.ci.meta.Constant reverse(jdk.vm.ci.meta.Constant c,
                                       jdk.vm.ci.meta.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>

Specified by:

generate in interface ArithmeticLIRLowerable

mayNullCheckSkipConversion

public boolean mayNullCheckSkipConversion()

Description copied from interface: ConvertNode

Checks whether a null check may skip the conversion. This is true if in the conversion NULL is converted to NULL and if it is the only value converted to NULL.

Specified by:

mayNullCheckSkipConversion in interface ConvertNode

Returns:

whether a null check may skip the conversion
