Class PrimitiveValueProfile

java.lang.Object
com.oracle.truffle.api.utilities.ValueProfile
com.oracle.truffle.api.utilities.PrimitiveValueProfile
public class PrimitiveValueProfile extends ValueProfile
Represents a ValueProfile that speculates on the primitive equality or object identity of values.

Note that for {code float} and double values we compare primitive equality via Float.floatToRawIntBits(float) and Double.doubleToRawLongBits(double), so that for example -0.0 is not considered the same as 0.0, even though primitive equality would normally say that it was.
