(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 | ||
- This problem is much, much easier than the rest and you should not base the difficulty of the other problems off of this one
