x86/x64的stack*****************************TBD

1.push parameter,

• %rdi，%rsi，%rdx，%rcx，%r8，%r9 用作函数参数，依次对应第1参数，第2参数。。。

2. push return address

3. push ebp,(current stack frame's base pointer)

jump to the caller.

4. push local variable.

5. sub esp to pre-allocate stack resource instead of push later.

其实stack frame上不止存放parameter->return address->ebp->local variable, compile还会根据便利挪作他用。

To be explain：他用。
