--- Comment #11 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
We just don't fold ptr < ptr that well:
_1 = (sizetype) i_5(D);
p_6 = &d[1] + _1;
if (&MEM <char[3]> [(void *)&d + 1B] > p_6)
If we change d to be a pointer argument we get:
p_5 = d_4(D) + 1;
_1 = (sizetype) i_6(D);
_10 = _1 + 1;
p_7 = d_4(D) + _10;
if (p_5 > p_7)
goto <bb 4>; [INV]
else
goto <bb 3>; [INV]
But that is PR 94356 (well if change pointer from type char to being int or
something different).
