--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I bet const on the function type is treated as __attribute__((const)) on it,
because the latter uses TREE_READONLY on the FUNCTION_TYPE.
Of course, the function really is const in the testcase, so optimizing the call
away is just fine, but bet if you change it such that it has side-effects it
would be miscompiled.
