Show the contents of the stack after the two marked points in the execution of the following code. Assume R0=0,R1=1,R2=2,R3=3,R4=4,R5=5, and R6=6. The initial stack pointer is 020001008. What is the contents of the stack (SP and contents) after execution point A and B ? PUSH {R2,R3} ADDR4,R1,R0; {R5,R6} ADDR5,R5,R4 ADD R6, R6, R5 PUSH {R0,R4,R5,R6}
