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 1 2 3 4 5 6 7 8 9 10 int foo(int a, int b) { int x, y; x = 123; y = a + b; return y; } int main() ...
Don't keep the frame pointer in a register for functions that don't need one. This avoids the instructions to save, set up and restore frame pointers; it also makes an extra register available in many functions. It also makes debugging impossible on some machines. On some machines, such a...
Backtraces were not accurate because go's function prelude stored the frame pointer past the edge of the stack. What did you expect to see? Accurate backtraces.
栈底指针寄存器(Stack Base pointer register):在16位系统中,有个寄存器叫bp;在32位系统中,这个寄存器叫ebp;在64位系统中,这个寄存器叫rbp。 栈顶指针寄存器(Stack pointer register):在16位系统中,有个寄存器叫sp;在32位系统中,这个寄存器叫esp;在64位系统中,这个寄存器叫rsp。 需要注意的是,栈底指针寄存器(...
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…

A frame pointer is a register which always contains the previous value of the stack pointer. On x86_64, the register in question is usually RBP. At the start of every function, a compiler with frame pointers enabled will generate code like this: Copy code snippet Copied to Clipboard Error:...
