'api_magic' LIR transformation replaces known Java API calls with platform dependent instruction sequences.

Example of Java API methods that can be replaced with IA32 instructions: 

java/lang/Integer.numberOfLeadingZeros
java/lang/Long.numberOfLeadingZeros
java/lang/Float.floatToRawIntBits
java/lang/Float.intBitsToFloat
various java/lang/Math methods
...
