请教一个问题，希望有缘人回答~ 书本上练习题4.35给了个例子，关于改变Execute阶段的转发源为E_dstE。答案给的例子有一点不太明白，为什么在修改过后的版本中，条件传送源值0x123被转发到ALU的输入valA，valB正确地得到了操作数值0x321了？ 我根据答案的例子绘出流水线图，对应`addq %rdx, %rdx`的decode阶段对应的`irmovq $0x312, %rdx`的write-back阶段，`%rdx`的值还没有写回寄存器文件，为什么答案说valB正确地得到了操作数值0x321了？
Hi Sakib, I read your solution website for OSTEP along with the book, and it helps me a lot. Thanks for the great web!👍 Anyway, I raise this issue here...
