1b (1 point) Suppose Jeff wrote the following assembly code fragment. We shall consider the above code for the next 2 questions addq %rbx, %raxline 1 movq %rax, (%rbx) ; line 2 movq $188, %rax ; line 3 Which of the following statement A-D is false? Circle E If you think they are all true A. There is a RAW dependency between line 1 and line 2 for register rax B. There is a WAR dependency between line 2 and line 3 for register rax. C. There is a WAW dependency between line 1 and line 3 for register rax. D. There is a WAR dependency between line 1 and line 2 for register rbx. E. None of the above 1c. (1 point) Which of the following statements A-C is false? Circle D if you think all are true A. Jeff should change the register rax in line 3 so to avoid stalling the pipeline unnecessarily B. Jeff should not worry about line 3 because the Intel superscalar design will take care of it via register renaming C. Line 1 and 2 shows a RAR dependency for register rbx. Because of this, if rbx is renamed to register rX during run-time, the intel processor will change register rbx in line 2 to rX too. D. None of the above
