在我的反汇编二进制文件（使用gcc -no-pie编译）文件中，我有以下内容：
00000000004017e0 <strstr@plt>:
4017e0: ff 25 32 0a 64 00 jmpq *0x640a32(%rip) # a42218 <_GLOBAL_OFFSET_TABLE_+0x218>
4017e6: 68 40 00 00 00 pushq $0x40
4017eb: e9 e0 fb ff ff jmpq 4013d0 <_init+0x20>
Disassembly of section .plt.got:
00000000004017f0 <.plt.got>:
4017f0: ff 25 d2 07 64 00 jmpq *0x6407d2(%rip) # a41fc8 <_DYNAMIC+0x1d0>
4017f6: 66 90 xchg %ax,%ax
4017f8: ff 25 da 07 64 00 jmpq *0x6407da(%rip) # a41fd8 <_DYNAMIC+0x1e0>
4017fe: 66 90 xchg %ax,%ax
后来我打来电话：
403ab7: e8 3c dd ff ff callq 4017f8 <strstr@plt+0x18>
有趣的精灵标题部分可能是：

问题是该指令（callq 4017f8）在这里如何工作？这似乎是调用.plt.got，然后跳转到不在重定位表中的某个地方。谁能解释一下呢？
