Q3: Instruction Analysis Q3A: What is the effect of executing STMIB R13! (RO-R2, R4)? Draw a picture of the state of the stack pointed at by R13 before and after this operation. Q3B: Two pair of instruction shown below. Does the instruction pairs shown above do exactly same things (Yes/NO) LDMIA R13! (RO-R2, R4) LDMFD R13! (RO-R2, R4) STMDB R13! (RO-R2, R4) STMFD R13! (RO-R2, R4) Q3C: If your answer to Question Q3B is Yes, why do these two instruction pairs have different suffix (IA,FD) or (DB,FD
