Note: Use brief English descriptions for lines that have no C equivalent such as test of a register, and manipulating the stack pointer a. b. Trace the execution of compute (-3). Write the line number of each line that is being executed and write the values of the registers after execution of that line Show what you know about condition codes and whether branches are taken or not. Take particular note of any procedure calls and returns. Here is a start on your answer Line rdi raxcondition codesotes (This is the entry values) 3 c. What is the final return value of compute (-3)? d. What is compute actually computing
