In some assembly code, I find that this register is often used with sp register or alone,and sometimes causing problems.
In fact, I'm not very familiar about its special usage in ARM architecture.
Can someone tell me about it and what I should pay attention to when using it ?
Hello,
I'm not a specialist but normally the r11 no have special problem with the sp in user mode. Can you give us a little more explanation of the problem that gives you trouble ? http://image.slidesharecdn.com/arm1-140401220608-phpapp02/95/the-arm-architecture-arm-arm-architecture-11-638.jpg?cb=139…
