gdb如何使用寄存器作为地址并显示偏移内容？
How does gdb use register as address and display offset content?
在 gdb 中：
p $ebp #will print content pointed by ebp
p 4$ebp # gdb says this is illegal operand.
我想显示ebp指向的地址后的4个字节，显示一个int。如何在gdb中指定这个命令？
p $ebp #will print content pointed by ebp
不，它将打印 $EBP 的 值 。
I wish to show 4 bytes after the address pointed by ebp, and display an int.
(gdb) x/x $EBP+4
(gdb) x/d $EBP+4
(gdb) p *(int*)($EBP+4)
在 gdb 中：
p $ebp #will print content pointed by ebp
p 4$ebp # gdb says this is illegal operand.
