咨询，ebp指向栈顶，那么直观的看是指向上面，还是下面？

Question

push ebp+---------+
+ 参数M  +
+ --------+
+ return  +
+---------+<-----ebp
+old ebp +
+             +
+++++++ <-----esp
+             +
+             +
+---------+move ebp  esp
+---------+
+ 参数M  +
+ --------+<---ebp+8
+ return  +
+---------+<---ebp+4
+old ebp +
+             +
+++++++ <----ebp = esp
+             +
+             +
+---------+我的理解应该是这样吧，为啥看有的书里面总是下面这样的呢？
+---------+
+ 参数M  +
+ --------+<-----ebp+4是参数M
+ return  +
+---------+<-----ebp指向return address
+old ebp +
+             +
+++++++ 
+             +
+             +
+---------+

Answer 1

ebp指向的是栈底啊， esp 才是指向栈顶，确定没搞错？（Intel 栈是从高地址向低地址增长的）push ebp+---------+
+ 参数M  +
+ --------+
+ return  +
+---------+<-----ebp
+old ebp +
+             +
+++++++ <-----esp
+             +
+             +
+---------+move ebp  esp
+---------+
+ 参数M  +
+ --------+<---ebp+8
+ return  +
+---------+<---ebp+4
+old ebp +
+             +
+++++++ <----ebp = esp
+             +
+             +
+---------+push  eax
+---------+
+ 参数M  +
+ --------+<---ebp+8
+ return  +
+---------+<---ebp+4
+old ebp +
+++++++ <----ebp
+   eax     +
+++++++<--- esp
+             +
+             +
+             +
+---------+

Answer 2

入栈： 先 - 4，再把数据拷贝到 esp 指向的地址
出栈：先把数据复制出来，然后 + 4
