Assume the CPU is executing a function that has local variables $x,y,$ and $z$ allocated

on the stack, and that $x$ is allocated at the memory address that is $16$ bytes from the

address value stored in register sp$,$ or $[$sp$,$ #$16].$ Assume y is stored at $[$sp$,$ #$8],$ and

$z$ is at $sp.$ For the assembly code and register values listed below:

$(1)$ Show the values that will be stored in the registers and in memory when

execution of these instructions is complete. If the value is unknown, write $"?".$

$(2)$ Write a C code translation of the assembly code sequence. You may assume

that $x,y,$ and $z$ have already been declared as long variables in the $C$ code. You do

not need to write the entire function, just the lines of $C$ that might have generated

the ARM$64$ instructions. Hint: one solution is $4$ lines of C code.

C Code Translation

mov x$0,$ #$2$

mov x$1,$ #$3$

str x$0,[$sp$,$ #$16]$

str x$1,[$sp$,$ #$8]$

add x$0,$ x$0,$ x$1$

str x$0,[$sp$]$

lsl x$1,$ x$1,$ #$1$

str x$1,[$sp$,$ #$8]$
