--- Comment #16 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to H.J. Lu from comment #14) > Created attachment 51556 [details] > The v5 patch > > Changes in v5: > > 1. Check SSA_NAME before SSA_NAME_OCCURS_IN_ABNORMAL_PHI. Why don't you just move this to match.pd instead as suggested by Richard B. on the mailing list? Then you get the check for SSA_NAME_OCCURS_IN_ABNORMAL_PHI for free and such. Plus other passes will do the optimization too ....
