Compilers, like programmers, can introduce inefficiencies while translating source language into IR. As a result, the compiler’s optimizer is very important in removing these inefficiencies. Give two examples of inefficiencies you would expect an optimizer to improve. Give two examples of inefficiencies you would expect an optimizer to miss, even though they can be improved. Explain why an optimizer would have difficulty improving them. (8 points)
