Graal Intrinsification Extensions

[Curt Albert]

I am a student at Virginia Tech interested in graal. I was looking over the
slides from the jvm lang summit and found the intrinsification extension
example. However when looking through code I could not find this ever
implemented anywhere. I was wondering if someone could help me get the
example running. Does it matter where the IntrinsifierImpl class code is?
Does it go in graal itself and if so where or in my java source file?

Thanks,
Curt Albert
