--- Comment #19 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Jakub Jelinek from comment #18) > > For bitfields there's also the ever present bitfield-lowering idea... > > I understood Andrew P. is working on something, but no idea how far it is. I am working towards regression free. I have most of it completed, the store merging regression is the main thing which is blocking it. > > > And the fact that optimize_bit_field_compare is done way too early. > > Agreed on that. Agreed there too.
