Programming Problem #1: 16-bit add (macro) Similar to #5 on Page 239) Define a macro that takes 4 argum ents in 4 registers representing two 16-bit integers and places the result of adding them together into 2 of the registers. In particular, the macro will create a pseudo-instruction with the following format Addw ah, al, bh, bl It represents the operation ah : a ah : a1 + bh : b1. Include concise documentation that describes the macro Programming Problem #1: 16-bit add (macro) Similar to #5 on Page 239) Define a macro that takes 4 argum ents in 4 registers representing two 16-bit integers and places the result of adding them together into 2 of the registers.
