--- Comment #21 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 47069 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=47069&action=edit gcc10-prereload-splitters.patch Ah, apparently we already have for ~ 2 years a property to handle this safely. So perhaps following incremental (so far completely untested) patch? It unfortunately requires the two generic changes, the alternative would be to add a helper function somewhere in i386*.c which would return can_create_pseudo_p () && !(cfun->curr_properties & PROP_rtl_split_insns); declare it in i386-protos.h and just use it in config/i386/*.md instead. Any preferences? From maintainance POV, it might be cleaner to have the wrapper, but then the question is what is the best name for it.
