Printing 打印命令的Gdb语法

如何查看gdb中第一个操作数地址处的数据

cmp [ebp+eax], edi

我尝试使用：

print /d $ebp
print /d $eax

并手动添加值以生成地址，但不确定下一步要做什么，或者是否有更简单的方法

(gdb) help x
Examine memory: x/FMT ADDRESS.
ADDRESS is an expression for the memory address to examine.
FMT is a repeat count followed by a format letter and a size letter.
Format letters are o(octal), x(hex), d(decimal), u(unsigned decimal),
  t(binary), f(float), a(address), i(instruction), c(char) and s(string).
Size letters are b(byte), h(halfword), w(word), g(giant, 8 bytes).
The specified number of objects of the specified size are printed
according to the format.

例如：

x/d $ebp+$eax

谢谢，这是我在x/d$ebp+eax中丢失的第二个美元符号
