要调试使用 PIN 工具的模拟器，通过使用 2 个不同的终端窗口，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
在另一个窗口上我执行以下操作：
gdb /home/agy/mcsim/Pthread/mypthreadtool

Continuing.
在某些时候，pin 工具冻结，我手动向 pin 工具发送中断信号，并尝试在附加窗口上调试它。为了了解引脚实现卡在哪一行，我尝试了 backtrace 命令，但即使添加了符号文件，它也会返回问号。
Program received signal SIGINT, Interrupt.

我在这里找不到错误的方法。你能帮我吗？
我在这里找不到错误的方法。
您告诉 GDB
mypthreadtool/home/agy/mcsim/pin/intel64/bin/pinbin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
想要刷新生成的新提示以及如何导航
打开 2 个终端并导航到以下命令：
$ cd source/tools/ManualExamples
在一个终端中
$ make DEBUG=1 lab0.cpp // compile the pintool to be debugged with this flag
$ ../../../pin -pause_tool 30 -t obj-intel64/lab0.so -- /bin/ls
暂停 30 秒以附加到 pid 31946 的进程
要将调试信息加载到 gdb，请使用：
设置 sysroot /not/existing/dir
文件
添加符号文件 /home/jasneetsingh/Desktop/pintool/pin-experiments/source/tools/ManualExamples/obj-intel64/lab0.so > 0x7f8eef3993d0 -s .data 0x7f8eef51a9c0 -s .bss 0x7f8eef51b3c0
在另一个终端
$ sudo gdb ../../../pin
...
(gdb) attach 31946
(gdb) set sysroot /not/existing/dir
(gdb) file
...
Are you sure you want to change the file? (y or n) y
(gdb) add-symbol-file /home/jasneetsingh/Desktop/pintool/pin-experiments/source/tools/ManualExamples/obj-intel64/lab0.so 0x7f8eef3993d0 -s .data 0x7f8eef51a9c0 -s .bss 0x7f8eef51b3c0
( y or n) y
(gdb) b main
现在可以开始调试了
