Figure 6:Layout of a stack frame. The frame pointer points just below the last argument passed on the stack. The stack pointer points to the first word after the frame. Figure6shows a diagram of a stack frame. A frame consists of the memory between the frame pointer ($fp), which point...
這幾天在複習 compiler 有關 runtime environment 的章節,讀到 activation record 的時候發現對 frame pointer 的概念有點忘記了,於是就決定來做一點小實驗。 Toy example 12345678910 intfoo(inta,intb) {intx, y;x=123;y=a+b;returny;}intmain() {foo(111,222);} ...
omit-frame-pointer 开启该选项,主要是用于去掉所有函数SFP(Stack Frame Pointer)的,即在函数调用时不保存栈帧指针SFP,代价是不能通过backtrace进行调试根据堆栈信息了。通过去掉SFP,可以提高程序运行速度,达到优化程序的目的。如果要打开栈指针,使用-fno-omit-frame-pointer。 另外一个类似选项-fomit-leaf-frame-pointer...
本文继续总结 Stack Unwinding。 我们知道实现 Stack Unwinding 的方法有很多。但常见的方法有两种:一种是 基于 Frame Pointer 的栈回溯;另一种是基于 Call Frame Information 的栈回溯。基于 Frame Pointer 的…

The error comes from the factor that the debugger requires the frame pointer information to properly display the call stack in the debug view. Hope this helps, Rafael Up0TrueDown shuyan HOU14 年多前in reply toLisa TI Prodigy150points
The /Oy compiler option makes using the debugger more difficult because the compiler suppresses frame pointer information. If you specify a debug complier option (/Z7, /Zi, /ZI), we recommend that you specify the /Oy- option after any other optimization compiler options. To set this compiler...
