| This testcase failed because host_integerp (x, 0) was returning |
| 1 even for constants bigger than 2^31. It fails under under 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. */ |
