OopMap and C2 Intrinsics

             I am working on some C2 intrinsics that call into runtime C 
functions as opposed to stub routines and I occasionally run into 
crashes related to OopMap's. Looking online, it appears that a custom 
OopMap is required to be written for runtime functions that return 
objects/object references? Can someone point me in the right direction 
in regards to intrinsics and OopMap interactions?
