Hi, I'm trying expand the Float2Int pass in order to make it able to optimize expressions like f * x > y, where x and y are integers (we'll assume unsigned for simplicity) and f is a floating point constant. The optimization would convert the expression to something like: (a * x)/b > y where a and b are integers guessed by the compiler (currently using continued
