By using several gnu compiler extensions for application profiling , the addr2line utility for address translation , and the graphviz program for graph visualization , you get a program that profiles an application and then presents a directed graph illustrating the call chains 通過使用對應用程序進行分析的幾個gnu編譯器擴展,可以使用addr2line工具進行地址轉換,并對graphviz應用程序進行圖形可視化,然后您就可以得到一個程序,該程序可以對應用程序進行分析,并展示一個說明調用鏈的定向圖。
