--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
It is not just ICE, but also a wrong-code starting with GCC 4.3:
int x, y;
__attribute__((noipa)) int
foo (int z)
{
if (__builtin_expect (x ? y != 0 : 0, z++))
return 7;
return z;
}
int
main ()
{
x = 1;
asm volatile ("" : "+m" (x), "+m" (y));
if (foo (10) != 11)
__builtin_abort ();
return 0;
}
The side-effects of the second __builtin_expect argument are evaluated multiple
times.
