[Bug tree-optimization/34864] array constants after inlining and "staticification"

[pinskia at gcc dot gnu dot org]

------- Comment #1 from pinskia at gcc dot gnu dot org  2008-01-19 12:04 -------
It is constant folded but not until after inlining.
A simplier example is:

static inline int f(int a)
{
  return a+2;
}

int g(int a)
{
  const int b[] = {f(1), f(2), f(3) };
  return b[a];
}
int g1(int a)
{
  const int b[] = {(1)+2, (2)+2, (3)+2 };
  return b[a];
}

---- CUT ----
Where g and g1 could produce the same code if wanted to.
