84 CHAPTER 5. <strong>MIPS</strong> ASSEMBLY CODE EXAMPLES 5.8 fib-o.asm This program is described in section 3.1.1.3. This is a (somewhat) optimized version of a program which computes Fibonacci numbers. The optimization involves not building a stack frame unless absolutely necessary. I wouldn’t recommend that you make a habit of optimizing your code in this manner, but it can be a useful technique. 1 ## Daniel J.
