This is IV-opts going funny I think as we get pointer+pointer (and yes real
pointer SSA_NAMES and no casts).

This code itself is very weird and I don't know if it is really defined or not.
We have basically:
char *f(char *a, char *b)
{
return a + (int)b;
}
How can that even be defined.
Anyways the following fixes the problem:

This is a different bug, related to the alpha backend was not fix up
for pointer plus.
Please file seperately.

Andrew, do you want to convert to sizetype or to ptrdiff_t? Does it matter?

(In reply to comment #9)
> Andrew, do you want to convert to sizetype or to ptrdiff_t? Does it matter?
sizetype is correct for POINTER_PLUS_EXPR. We don't have a ptrdiff_t
internally inside GCC as far as I know, only ssizetype (the signed version of
sizetype).
I am testing this patch right now and should be done in about 2 hours.
