Lecture Quiz on Sim5    

The function "main()" calls function "%r0=one()" and outputs the number returned in %r0. 
Function "%r0=one()" simply calls function "%r0=two()" and returns. Function %r0=two()
sets %r0 equal to 100 and returns. 

Write the assembly language code for main(), one(), and two(). Remember that %r7 is the
stack pointer, %r8 is the return address register, and %r9 is the instruction pointer.
