I don't think any of us know what you mean by "how many times expressions are simplified." Can you be more specific? Can you provide an example of what you want to look for, and an example of what you do not want to look for?
How many times gcc simplify expressions like: x/x, 0*x, 1*y, a+0, x*x/x and so on
