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(yīng)用程序進(jìn)行分析的幾個gnu編譯器擴(kuò)展,可以使用addr2line工具進(jìn)行地址轉(zhuǎn)換,并對graphviz應(yīng)用程序進(jìn)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(yīng)用程序進(jìn)行分析,并展示一個說明調(diào)用鏈的定向圖。
