1.调试命令s或step (gdb) s 4 for (i=1;i<=n;i++) (gdb) p i $11 = 0 1. 2. 3. 4. 可以看到执行命令s之后,出现了一行4 for (i=1;i<=n;i++),这代表着即将执行的一行,我们打印i的值可以看到,此时的i的值仍然是0...

CUDA-GDB allows the user to set breakpoints, to single-step CUDA applications, and also to inspect and modify the memory and variables of any given thread running on the hardware. CUDA-GDB supports debugging all CUDA applications, whether they use the CUDA driver API, the CUDA runtime API,...

This question is a little unclear to me, but I'll take a stab: If you have GDB attached to the crashing process when it crashes, a crash should stop the program and put you back at the (gdb) prompt. If you then type bt, you should see the stack. If you do NOT have GDB attach...
GDB is not stepping into either of the shared libraries. btgives the name of the function where the problem occurred, butlistshows code inmy-program-src.cpp All code is compiled with the following options: gcc -MD -D__LINUX__ -g -Wall -Wextra -Iinc -m32 -fpic -I../../publ...
Looks likepcalways has an even value in GDB on the FX3, so I guess the current behavior is fine. Though, I should probably support all the mode-banked registers as well, that's currently not implemented. Sadly there's no way to get a good register index↔name linking afaik, so time...
A debugger is software that runs your code and examines any problems it finds. GNU Debugger (GBD) is one of the most popular debuggers, and in this article, ...
