摘要

本文提出了可扩展的C/ c++全程序调用图工具MetaCG。我们介绍了它的图形库、基于clang的工具CGCollector来构造调用图并附加元信息，以及CGValidate来检查给定特定执行的缺失边。MetaCG通过其元数据功能-注释机制提供可扩展性，以便在工具之间传递信息。它保留继承层次结构，并且可以序列化为JSON。我们评估了CG-Collector为C/ c++代码构建整个程序调用图的能力，并随后提出了一个性能分析器和一个内存清理器，它们依赖于MetaCG来获取整个程序调用图信息

MetaCG: annotated call-graphs to facilitate whole-program analysis

The paper presents the extendable C/C++ whole-program call-graph tool MetaCG. We introduce its graph library, the Clang-based tool CGCollector to construct the call graph and attach meta information, and CGValidate to check for missing edges given a particular execution. MetaCG offers extendability through its metadata function-annotation mechanism to transfer information between tools. It preserves inheritance hierarchies and can be serialized into JSON. We evaluate CG-Collector’s ability to construct whole-program call-graphs for C/C++ code and, subsequently, present a performance profiler and a memory sanitizer that rely on MetaCG for whole-program call-graph information
