[Bug tree-optimization/36352] New: missed "inlining" of static untouched variable in linked once function

[pinskia at gcc dot gnu dot org]

While looking into PR 36297, I found this interesting missed optimization, it
only happens with linked once functions.  Testcase:
template <int a> int f(void)
{
  static int t = a;
  return t;
}

int g(void)
{
  return f<1>();
}

We should produce return 1 for both functions but currently we reference
f<1>::t .
