988 # This causes an anomaly in the results of make -n
989 # because insn-* is older than stamp-*
990 # and thus make -n thinks that insn-* will be updated
991 # and force recompilation of things that depend on it.
992 # We use move-if-change precisely to avoid such recompilation.

997 # to recompile insn-*.o. To avoid problems and extra noise from
998 # versions of make which don't like empty commands (nothing after the
999 # trailing `;'), we call true for each.
