-// This file contains a GCStrategy which serves as an example for the usage
-// of a statepoint based lowering strategy.  This GCStrategy is intended to
-// suitable as a default implementation usable with any collector which can
-// consume the standard stackmap format generated by statepoints, uses the
-// default addrespace to distinguish between gc managed and non-gc managed
-// pointers, and has reasonable relocation semantics.
