1078  The trace_assign_type is a verifier that the entry type is* the same as the type being assigned. To add new types simply* add a line with the following format:* IF_ASSIGN(var, ent, type, id);* Where "type" is the trace type that includes the trace_entry(field, entry)
1079  saved等于field
1080  返回:print_graph_entry( & saved, s, iter, flags)
