c++ - 调试 PIN 工具添加符号文件不起作用

Question

要使用 2 个不同的终端窗口调试使用 PIN 工具的模拟器，我执行以下操作:

/home/agy/mcsim/pin/intel64/bin/pinbin -pause_tool 5 -t /home/agy/mcsim/Pthread/mypthreadtool -port 47145 -skip_first 10000 -- McSim/JacNoBoost/JACCARD
Pausing to attach to pid 5465
To load the tool's debug info to gdb use:
   add-symbol-file /home/agy/mcsim/Pthread/mypthreadtool 0x7f86e6c06ee0 -s .data 0x7f86e709f620 -s .bss 0x7f86e70aaac0

在另一个窗口中，我执行以下操作:

gdb /home/agy/mcsim/Pthread/mypthreadtool

Continuing.

在某些时候，pin 工具卡住，我手动将中断信号发送到 pin 工具并尝试在附加窗口上调试它。为了解哪一行 pin 实现卡住了，我尝试了 backtrace 命令，但它返回时带有问号，即使添加了符号文件也是如此。

Program received signal SIGINT, Interrupt.

我在这里找不到错误的方法。你能帮帮我吗？

I couldn't find the wrong approach here.

您告诉 GDB mypthreadtool 是您的主要可执行文件，但它不是:/home/agy/mcsim/pin/intel64/bin/pinbin 是。

试试这个:

gdb /home/agy/mcsim/pin/intel64/bin/pinbin 5465
(gdb) add-symbol-file /home/agy/mcsim/Pthread/mypthreadtool \
    0x7f86e6c06ee0 -s .data 0x7f86e709f620 -s .bss 0x7f86e70aaac0
