-//===-- CoreCLRGC.cpp - CoreCLR Runtime GC Strategy -----------------------===//

-//===----------------------------------------------------------------------===//
-//
-// This file contains a GCStrategy for the CoreCLR Runtime.
-// The strategy is similar to Statepoint-example GC, but differs from it in
-// certain aspects, such as:
-// 1) Base-pointers need not be explicitly tracked and reported for
-//    interior pointers
-// 2) Uses a different format for encoding stack-maps
-// 3) Location of Safe-point polls: polls are only needed before loop-back edges
-//    and before tail-calls (not needed at function-entry)
-//
-// The above differences in behavior are to be implemented in upcoming checkins.
