;;- instruction definitions

;;- See file "rtl.def" for documentation on define_insn, match_*, et. al.

;;- 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 
;;- gmicro; no compares are eliminated.

;;- 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.
