Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Even if you change this at the GIMPLE level, we still should check why expansion doesn't DTRT here. expand_builtin_memcpy has already all the needed store_by_pieces stuff. Let me have a look at that.
