Comment 2 Jakub Jelinek 2005-05-17 19:41:12 UTC 
Simplified testcase that ICEs at -O2:
struct S
{
  void *s[256];
};

struct T
{
  long t[23];
  struct S *u;
};

extern struct T
#ifdef __ia64__
__attribute__((model (small)))
#endif
v;

void *
foo (void)
{
  return v.u->s[0];
}
Comment 3 Dave Jones 2005-05-18 00:24:30 UTC 
the bizarre thing -- this code hasnt changed recently, and it has built fine in
the previous build. Did we recently upgrade the gcc in the buildroot ?
Comment 4 Jakub Jelinek 2005-05-19 07:49:37 UTC 
Should be fixed in gcc-4.0.0-7.
