--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
As I wrote on IRC, I fail to see what kind of conflict is there between
something previously declared pure and later declared const, const is just a
stronger pure, all const functions are necessarily pure.
With
__attribute__((pure)) int foo (int x, int y);
...
__attribute__((const)) int foo (int x, int y);
I see no harm, worst case some code will only assume the function is pure,
rather than const.
