Use ARM Assembly Code to write

Write push and pop functions. Each function needs to come back to appropriate locations in the calling section, use PC $($program counter$)$ to come back to the location where you branched. $($Hint: See Multiplication with program counter.$)$ You must keep track of the memory location where push will write, and pop will read the information. $($Hint: push$/$pop functions should locate at the end of your program.$)$

$(2)$ At the beginning of the program, store a memory address to a register. It is $0$x$1000$ for the example below.

$(3)$ Move a literal value to a register. It is our student ID$.$ One digit at a time.

$(4)$ Prepare register $12($or use BL for step $5),$ so that it will contain the return address from push.

$(5)$ Branch to push function.

$(6)$ Repeat step $35,$ so that eight digits of your student ID are pushed into a memory stack.

$(7)$ Prepare register $12($or use BL for step $8),$ so that it will contain the return address from pop.

$(8)$ Branch to pop function.

$(9)$ Move the popped value $($you may use one of the registers for holding the popped value.$)$ into register $1($R$1),$ for the first value, then R$2$ for the second, and so on$.$

$(10)$ Repeat step $79,$ so that $R1R8$ will be filled. The resulting order will be the reversed order of your student ID$.$
