The program used to generate the assembler output in Figure 1.5 is used in Fig 1.10 on two different computers; the assembler code below on the right is generated on a Macintosh G3 computer, the code on the left on a Pentium computer running Windows NT. Both machines use the same compiler: Metrowerks Codewarrior. A Pentium chip is shown in Figure 1.9 and a G3 chip is shown in Figure 1.11.

 What is similar in these two versions of assembly language and what is different? Can you find instructions that would be common to all the different assembly codes? Why do you think different compilers generate different code for the same program?
