Description
(Time 15 min)Write an assembly program called 64bitAdd.s that adds two 64 bit numbers together.
1. |
The first number will be referenced by the label num1 and the second number will be |
|||
referenced by the label num2. |
||||
2. |
The upper 32 bits of the sum should be placed in EDX and the lower 32 bits in EAX. |
|||
3. |
AFTER the last line of code that you wish to be executed in your program please place the |
|||
label done. |
||||
1. Make sure that there is an instruction after the done line and a new line after that |
||||
instruction. If you don’t your output won’t match mine. |
||||
4. |
I have included a Makefile for you that will compile your program. |
|||
5. |
IT IS OF VITAL IMPORTANCE THAT YOU NAME YOUR LABELS AS |
|||
SPECIFIED AND MAKE THE APPROPRIATE AMOUNT OF SPACE FOR EACH |
||||
VARIABLE! I will be using gdb to test your code and if your labels do not match then the |
||||
tests will fail. You must also make sure to include the done label AFTER the last line of |
||||
code you want executed in your program so that I know where to set break points. |
||||
6. |
The following table shows how the numbers will be laid out in memory. |
|||
num1: |
Upper 32 bits of num1 |
Lower 32 bits of num1 |
||
num2: |
Upper 32 bits of num2 |
Lower 32 bits of num2 |
||
7. This problem is much, much easier than the rest and you should not base the difficulty of the other problems off of this one
