--- Comment #9 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Here is a testcase which shows a similar issue where bseti is not used (ignore
the 1<<31 being undefined/unspecified issue):
int f(int a, int b)
{
  b = 31;
  int tt = sizeof(b)*8 - 1;
  return a | (((__typeof__(b))1) << (b & tt));
}
