[Bug c++/20912] C++ FE emitting assignments to read-only global symbols

Mon Apr 18 17:56:00 GMT 2005

------- Additional Comments From pinskia at gcc dot gnu dot org  2005-04-18 17:56 -------
Simple code which shows we now have a missed optimization:
static const double a = 1.0;
static const double b = a+1.0;

double c()
{
  return b;
}

See PR 21089.
