uftrace is a function call graph tracer for C, C++, Rust and Python programs. It hooks into the entry and exit of each function, recording timestamps as well as the function's arguments and return values. uftrace is capable of tracing both user and kernel functions, as well as library f...

其基本原理是给 GCC 打个补丁(如果你的gcc版本不符合它的要求还得先下载正确的gcc版本),让它在编译每个源文件时 dump 出其中函数的 call graph,然后用 Perl 脚本收集并整理调用关系,转交给Graphviz绘制图形(Graphviz属于后端,CodeViz属于前端)。 CodeViz 原本是作者用来分析 Linux virtual memory 的源码时写的一个...

Calltree is able to detect recursive function calls (e.g. functions that call themselves). Recursive function calls are marked with an ellipsis in the output. 这段问题大意是:calltree是一个针对C语言代码的静态分析工具。它可以以图像的形式产出函数的调用关系。但是calltree和cflow不一样,cflow使用...
is not completely correct and may not find all calls of a function. This is mainly true for calls that are done via function pointers. Calltree is able to detect recursive function calls (e.g. functions that call themselves). Recursive function calls are marked with an ellipsis in the ...
