;;- instruction definitions

;;- @@The original PO technology requires these to be ordered by speed,
;;- @@    so that assigner will pick the fastest.

;;- 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 in file tm.h handles condition code
;;- updates for most instructions.

;;- Operand classes for the register allocator:
;;- 'a' one of the address registers can be used.
;;- 'd' one of the data registers can be used.
;;- 'f' one of the CE floating point registers can be used
;;- 'r' either a data or an address register can be used.

;;- Immediate integer operand constraints:
;;- 'I'  1 .. 8
;;- 'J'  -32768 .. 32767
;;- 'K'  -128 .. 127
;;- 'L'  -8 .. -1

;;- Some remnants of constraint codes for the m68k ('x','y','G','H')
;;- may remain in the insn definitions.

;;- Some of these insn's are composites of several Alliant op codes.
;;- The assembler (or final @@??) insures that the appropriate one is
;;- selected.

;; We don't want to allow a constant operand for test insns because
;; (set (cc0) (const_int foo)) has no mode information.  Such insns will
