Thank you.
Sadly, for the example in comment #15, this is not quite enough, I need to add
forwprop+ccp right before the VRP1 pass (and then the range check is
eliminated, the vectorizer works and perfs are the

Ok, I have a patch that does the remaining (including the duplicate bug). But
for the (p + sz) - p case it can only optimize the sizeof (*p) == 1 without
range information - for example for
__SIZE_TYPE__

The original identity will remain. That is,

fx (int * b, int * e)

Another example: http://stackoverflow.com/q/21253690/1918193
where we have (-DVERSION=2):
_128 = img$_M_impl$_M_start_130 + 400;
pretmp_146 = (long intD.12) _128;
pretmp_145 = (long intD.12) img$_M_i

ptr1+(ptr2-ptr1) to ptr2
