- ;;- 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

- ;;- Operand classes for the register allocator:

- ;;- 'd' one of the data registers can be used.
- ;;- 'f' one of the m68881 registers can be used
- ;;- 'r' either a data or an address register can be used.
-
- ;;- Immediate Floating point operator constraints
- ;;- 'G' a floating point constant that is *NOT* one of the standard
- ;; 68881 constant values (to force calling output_move_const_double
- ;; to get it from rom if it is a 68881 constant).
