--- Comment #14 from Ilya Enkovich <ienkovich at gcc dot gnu.org> --- (In reply to Jakub Jelinek from comment #13) > So shall we still consider moving 32-bit stv pass before the combiner > instead of after it? The argument about andn is no longer relevant, we have > a one_cmpldi3_doubleword pattern now. Previously moving the pass caused regressions. If no regressions appear now then we should do it. It might enable some additional optimizations.
