         Resolution|---                         |FIXED

--- Comment #2 from Marc Glisse <glisse at gcc dot gnu.org> ---
We currently produce this .optimized:

foo (int i)
{
  void * saved_stack.2;

  <bb 2>:
  saved_stack.2_3 = 0B;
  GIMPLE_NOP
  return;

}

(and RTL finishes the cleanup)

cddce1 removes alloca
fab1 removes the stack save/restore

So I'm going to mark this as fixed.
