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)))

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.
