在我从http://en.wikibooks.org/wiki/X86_Disassembly/Functions_and_Stack_Frames上读到函数和堆栈后,我对局部变量有疑问.
文章快照:
push ebp ; save the value of ebp
mov ebp, esp ; ebp now points to the top of the stack
sub esp, 12 ; space allocated on the stack for the local variables

这意味着可以通过引用ebp来访问局部变量.考虑以下C代码片段和相应的汇编代码:
a = 10;
b = 5;
c = 2;
mov [ebp - 4], 10 ; location of variable a
mov [ebp - 8], 5 ; location of b
mov [ebp - 12], 2 ; location of c

请记住,推送基本上是这样的:
