[Refer SD 6.3.7] Consider the following C code snippet. void setArray(int num) { int i; int array[10]; for (i = 0; i = 0) return 1; else return ; } int sub(int a, int b) { return a - b; } A. Implement the C code snippet in ARM assembly language. Use R4 to hold the variable i. Be sure to handle the stack pointer appropriately. The array is stored on the stack of the setArray function. B. Assume setArray is the first function called. Draw the status of the stack before calling setArray and during each function call. Indicate the names of registers and variables stored on the stack, mark the location of SP, and clearly mark each stack frame. C. How would your code function if you failed to store LR on the stack?
