Well, then you all believe in Santa Claus ;-)
It's generally not possible for the compiler to optimise divisions into
multiplications and shift because if data are not known constants, it can't
predict that the smashed bit aren't usefull anyway, and if data are known
constants, well, everything can be computed at compilation.
