- * The output of the SCC analysis is passed to the `cross_references()`
- * callback. It is expected to set the `is_alive` flag on those strongly
- * connected components that it wishes to be kept alive. Only bridged objects

+ * The output of the SCC analysis is passed to the client's `cross_references()`
+ * callback. This consists of 2 arrays, an array of SCCs (MonoGCBridgeSCC),
+ * and an array of "xrefs" (edges between SCCs, MonoGCBridgeXRef). Edges are
+ * encoded as pairs of "API indices", ie indexes in the SCC array. The client
+ * is expected to set the `is_alive` flag on those strongly connected components
+ * that it wishes to be kept alive.
