-
- ;;- When naming insn's (operand 0 of define_insn) be careful about using
- ;;- names from other targets machine descriptions.
-
- ;;- cpp macro #define NOTICE_UPDATE_CC is essentially a no-op for the

-
- ;;- The original structure of this file is m68k.md.
-
- ;; ??? Work to be done:
- ;; Add patterns for ACB and SCB instructions.
- ;; Add define_insn patterns to recognize the insns that extend a byte
- ;; to a word and add it into a word, etc.
-
- ;;- Some of these insn's are composites of several Gmicro op codes.
- ;;- The assembler (or final @@??) insures that the appropriate one is
- ;;- selected.
