-        * Makefile.in (HOST_CFLAGS): Take out -DGENERATOR_FILE.
-        (CONFIG_H, TCONFIG_H, TM_P_H): Update.
-        (GEN, STAGESTUFF): Add new files.
-        (insn-constants.h, s-constants, tm-preds.h, s-preds,
-        genconstants, genpreds, genconstants.o, genpreds.o): New rules.
-        (hashtab.o, safe-ctype.o): Add -DGENERATOR_FILE.
-        * mkconfig.sh: Include tm-preds.h in tm_p.h; insn-constants.h
-        as well as insn-codes.h and insn-flags.h in config.h; and no
-        extra headers in tconfig.h and hconfig.h.
-
-        * gencodes.c: Eliminate code to generate predicate declarations
-        or #defines for md-file constants.
-        * genconstants.c, genpreds.c: New files.
-
-        * i386.md: Re-order guard expressions such that TARGET_64BIT
-        comes first, when this permits better optimization.  Add
-        TARGET_64BIT to more x86-64 patterns.  Add comment explaining
-        why this is desirable.
