/* 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. */ /* { dg-do run } */ /* { dg-options "-O2" } */ /* { dg-options "-O2 -mdisable-indexing" { target hppa*-*-hpux* } } */ /* { dg-skip-if "" { "ia64-*-hpux*" } "*" "-mlp64" } */ /* Disable the test entirely for 16-bit targets. */ #if __INT_MAX__ > 32767 extern void abort (void); extern void exit (int); struct A { int a[10000][10000]; }; int b[2] = { 213151, 0 }; void foo (struct A *x, int y) { if (x->a[9999][9999] != x->a[y][y]) abort (); if (x->a[9999][9999] != 213151) abort (); } int main (void) { struct A *x; asm ("" : "=r" (x) : "0" (&b[1])); foo (x - 1, 9999); exit (0); } #else int main () { return 0; } #endif /* __INT_MAX__ */
