2. (5 pts) Write a working Assembly macro code labeled 'add2' that is called from your main' routine and uses the "register passing" parameter technique. Your 'main' routine should: a. pass two parameters (x,y) into the macro 1 of 3 b. store the macro resul into a memory location labeled 'sum:'. The macro 'add2' does the following: a. accepts two parameters "REG1 and REG2" b. Adds REG1 and REG 2 and stores the result in REG3 c. Returns to your 'main' routine.
