NOTE: The following questions are asking about the Intel 8086 processor assembly language, and are modified from questions in Chapter 8 of The Art of Assembly Language by Randall Hyde. 1. ADC and SBB can be forced to behave exactly like ADD and SUB by inserting some other instruction before ADC and SBB. What instruction must be inserted in front of ADC to make it behave like ADD? In front of SBB to make it behave like SUB? 2. Given that you can manipulate data items on the top of stack using PUSH and POP, explain how you could modify a return address on the top of stack so that a RET instruction will cause the 80x86 to return two bytes beyond the original return address. 3. Provide four different ways to add two to the value in the BX register. No way should require more than two instructions (hint, there are at least six ways of doing this!) 4. Explain the difference between the carry flag and the overflow flag
