I'll try to do MULT_EXPR later so that for -10<i<10 and -10<j<10 > we > get the same range for (unsigned)(i*j) and (unsigned)i*(unsigned)j. Btw, now that I have committed the TYPE_IS_SIZETYPE changes I have some pending VRP patches that I like to push (I'm not sure if they covert this, I have to revisit them first).
