Stack Operation 10. (10 pts.) Show the contents of the stack and affected registers at the two marked points in the execution of the followin code. Assume RO-0, R1-1, R2-2, R3-3, R4-4, R5-5, and R6-6. The initial value for stack pointer (prior to executing this code block) is given as SP-0x20001000 PUSH R2,R3) ADD R4, R1, Re ;<---A POP R5, R6) ADD R5, R5, R4 ADD R6, R6, R5 PUSH (R4-R6); SUBS Re, RO,R1-B a) Show the contents of Stack,...

Say R1 = 5, R2 = 6. Push or pop the following registers to the stack and see if they are equal. Specify the top and bottom of the stack. push {r2, r1} pop{r2, r1} AND push {r1, r2} pop{r2} pop{r1} AND Push {r1} Push{r2} Pop {r1, r2} Are these operations equivalent?

Assume the stack pointer (SP) is initialized to 0x20000000 . Registers RO, R1, R2 and R12 are initialized to 2, 3, 8 and 15 respectively. Answer the following: Show the content of the stack and the SP after the following sequence of operations. PUSH (R12} PUSH {R1-R2} PUSH (RO) Answer format example=> {1,2,3,4} if 1,2,3,4 are values in stack and with no spaces.
