Yes. I know it doesn't fail on IA64-HPUX. The reason is
that the dereferencing expression has been transformed as:
tmpvar = index+offset;
*tmpvar;
during induction variable optimization, Where tmpvar has SImode.
PPC has different costs to compute induction variables as on IA64-HPUX.

I do not see this failing on ia64-hpux (with -milp32).

Are you sure that you are not doing something funny with your
port?
