/* PR c/4389
   This testcase failed because host_integerp (x, 0) was returning
   1 even for constants bigger than 2^31.  It fails under under hppa
   hpux without -mdisable-indexing because the pointer x - 1 is used
   as the base address of an indexed load.  Because the struct A is not
   actually allocated, x - 1 lies in the text segment and this causes
   the wrong space register to be selected for the load.  It fails on
   IA64 hpux in ILP32 mode because extending x - 1 before adding the
   array offset gives a different answer then adding first and then
   extending.  The underlying problem is the same as with hppa, x - 1 is
   not a legal data address.  It also fails on x32 targets for the
   same reason.  */
