   This testcase failed because host_integerp (x, 0) was returning
3
   1 even for constants bigger than 2^31.  It fails under under hppa
4
   hpux without -mdisable-indexing because the pointer x - 1 is used
5
   as the base address of an indexed load.  Because the struct A is not
6
   actually allocated, x - 1 lies in the text segment and this causes
7
   the wrong space register to be selected for the load.  It fails on
8
   IA64 hpux in ILP32 mode because extending x - 1 before adding the
9
   array offset gives a different answer then adding first and then
10
   extending.  The underlying problem is the same as with hppa, x - 1 is
11
   not a legal data address.  */
