--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Andrew Pinski from comment #3) > cmov optab is unused (PR120230). > Which means this is fixed for GCC 4.5.0. > I am testing a patch to remove cmov optab right now too. cmov was removed in r16-572 (but it was never used so documentation does not matter in the end).
