[Bug middle-end/35992] [4.4 Regression] Linux kernel code fails to compile with -Os

[pinskia at gcc dot gnu dot org]

------- Comment #2 from pinskia at gcc dot gnu dot org  2008-04-20 19:50 -------
Caused by:
  size = size_in_bytes (TREE_TYPE (TREE_TYPE (base)));
  if (size == NULL_TREE || TREE_CODE (size) != INTEGER_CST)
    return true;

in pointer_may_wrap_p.

a simple s/size_in_bytes/TYPE_SIZE_UNIT/ should fix the problem.
