For problems that require development of a program test the solutions with data values selected to cover the widest possible range of situations. For problems which require the development of only part of a program devise a test program with additional instructions to enable the partial program to be fully tested. 4.4 a) b) Assume that register r2 holds the value 0x0f45, what is the value in register r5 after the execution of the instruction SUB r5, r2, 209 ? Assume that register r2 holds the value 0x045, what is the value in register r5 after the execution of the instruction RSB 25, 72, #209 ? What problems arise when register r2 holds Ox0f45 and the instruction RSS r5, r2, 209 is executed? What will be the value in register r5 after the execution of this instruction? c) 4.5 a) b) What is the value in register r8 after the execution of the instruction MVN r8, Oxf4 ? Assume that register r3 holds the value 0x045 and r10 holds Oxffit; what is the value in register r3 after the execution of the instruction ADD 13, r3, r10? Describe the form of the value that will be in register r6 after the execution of the instruction ADD 26, r6, #1 ? c)
