2 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. It also fails on x32 targets for the
14 /* { dg-options "-O2" } */

17 /* { dg-skip-if "" { { i?86-*-* x86_64-*-* } && x32 } { "*" } { "" } } */
