   I have created this linked list at the end of the file (in data seg):

   The List object struct is as follows:

                 int value;     // Offset = 0
                 List next;     // Offset = 4

	// Load the value in variable head.value into r10
	// Load the value in variable head.next.value into r10
	// Load the value in variable head.next.next.value into r10
