Assume the stack pointer (SP) is initialized to 0x20000000 . Registers RO, R1, R2 and R12...
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?
Show the stack contents, registers contents and the stack pointer value for each step of the following code: Mov R5,#25H Mov R6,#15H Mov R1,#20H Push 5 Pop 2 Mov R2, #55H Push 2 Push 6 Pop 5 9
