--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Yeah, -fexcess-precision= is not an option for C++, but still, if you use
-ffloat-store, you need to be prepared for severe performance degradation.  If
you have several levels of abstraction as you have in the std::array case, you
need to accept that those abstractions might introduce some extra stores.
