------- Comment #8 from jakub at gcc dot gnu dot org 2008-12-02 17:50 ------- "I guess that option 4 is to investigate why DSE doesn't remove the dead stores." 1) DCE which removes this is done after DSE2 2) DSE doesn't remove sp based stores, except for spill slots (there is a PR about it, but isn't going to be fixed any time soon).
