Profiling works by changing how every function in your program iscompiled so that when it is called, it will stash away some informationabout where it was called from. From this, the profiler can figure outwhat function called it, and can count how many times it was called.This change is ...

经过一番分析和调查,终于找到原因,因为perf_dl.out文件的输出工作是在主程序执行结束之后、系统回收资源的时候 调用的(具体见实现原理一节),而在此时主程序执行了dlclose()函数卸载了libtestprofiler.so,所以随后dump出的内存映射 表当然就不会包含libtestprofiler.so的信息了。我们测试下将dlclose(dl_handle)注释后...
