CS 213 Fall 2000 Homework H1a

Notes

• As solutions, the original C code can be found in the file /afs/cs.cmu.edu/academic/class/15213-f00/H1a/probs-solve.c.
• Note that you are required to work on this assignment individually. Note also that this assignment will have only a small effect on your grade. It's purpose is to give you some useful practice, not to determine your course grade. You'll find this practice very useful in preparing you for Lab 2.
• The assignment handout suggests you try to make your C code generate assembly code that is syntactically identical to the given assembly. That's a good goal, but don't waste too much time trying to achieve it. Depending on small variations in the C code, GCC will generate different register allocations, different instruction orderings, and other minor variations that have no effect on functionality. The grading of the assignment will be based purely on whether your code matches the functionality of the given code.
• Sept 15, 14:00. The atest code uses the wrong names for the last 3 procedures. To test these three you would refer to them as if, while, or for when using the -f argument for atest, rather than ifcode, whilecode, and forcode, respectively. You can either retrieve the modified .tar file, or just use the shorter names. [Bug caught by Deryck Morales.]
