--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Maybe i386.c would need its own ix86_use_by_pieces_infrastructure_p target hook if the default wouldn't do the right thing with this. Maybe we'll need to split STORE_MAX_PIECES into separately overridable CLEAR_MAX_PIECES, SET_MAX_PIECES and STORE_MAX_PIECES macros, storing 32-byte or 64-byte zeros is cheap, but for e.g. store_by_pieces that might not be the case. And see what can be done to avoid the frame pointer.
