// { dg-do run { xfail arm-*-* sh-*-* ia64-hp-hpux* } }// NMS:2003-04-21 this fails on strict aligned architectures again,// the patch was reverted because it broke something more important.// Copyright (C) 2002 Free Software Foundation, Inc.// Contributed by Nathan Sidwell 8 Aug 2002 <nathan@codesourcery.com>// WRS SPR 63496, lost packed attribute when accessing a packed// field. This matters on aligned architectures like shstruct thing { int m; };struct pod { char a; thing m __attribute__ ((packed)); // { dg-warning "attribute ignored" "" { target default_packed } } };int main (){ thing t; pod p; p.m = t; /* runtime bus error here */ return 0; }
