/* 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. */
