Write an assembly language program to find the maximum of:

y = x⁶ - 14x² + 56x

for the range -2 ≤ x ≤ 4, by stepping one by one through the range. The program should include a macro de nition for xmax to be %l2, where xmax will be the value of x in the range above that results in the maximum value for y. Also de ne ymax to be %l3, where ymax is the maximum output obtained with input xmax. At the end of your code, after the values for xmax and ymax have been determined, place a label called done. This will be the label used to set a breakpoint with gdb for the TA to test your code. Also, make sure to de ne the values of the coecients 14 and 56 as constants a1 and a2 the TA may change these values to further test your code.

Try to eliminate as many nop instructions as possible and also try to minimize the length of your code. Run the program using gdb to verify correctness. Make sure to pay close attention to the requirements above.

Requirements:

1. Follow the requirements as described above.

2. Name your source le lastname3.m which is the le to submit. [It is a .m le rather than a .s le since you will have macro de nitions.]

3. To expand the macros and to create the .s assembly code le, run: m4 lastname3.m > lastname3.s
