+ * config/avr/builtins.def (DEF_BUILTIN): Factor out
+ "__builtin_avr_" from NAME, turn NAME to an uppercase identifier.
+ Factor out 'CODE_FOR_' from ICODE, use 'nothing' instead of '-1'.
+ Remove ID. Adjust comments.
+ * config/avr/avr-c.c (avr_builtin_name): Remove.
+ (avr_cpu_cpp_builtins): Use DEF_BUILTIN instead of for-loop.
+ * config/avr/avr.c (avr_tolower): New static function.
+ (DEF_BUILTIN): Remove parameter ID. Prefix ICODE by 'CODE_FOR_'.
+ Stringify NAME, prefix it with "__builtin_avr_" and lowercase it.
+ (avr_expand_builtin): Assert insn_code != CODE_FOR_nothing for
+ default expansion.

- DEF_BUILTIN(NAME, N_ARGS, ID, TYPE, ICODE)
+ DEF_BUILTIN(NAME, N_ARGS, TYPE, ICODE)
- NAME: The name as visible by the user as a C string.
+ NAME: `__builtin_avr_name' will be the user-level name of the builtin.
+ `AVR_BUILTIN_NAME' will be the internal builtin's id.
N_ARGS: Number of input arguments. If special treatment is needed,
set to -1 and handle it by hand, see avr.c:avr_expand_builtin().
- ID: An integer to identify the built-in.
TYPE: A tree node describing the prototype of the built-in.
- ICODE: Insn code number for the insn attached to the built-in.
- If special treatment is needed to expand the built-in, set to -1.
+ ICODE: Name of attached insn or expander. If special treatment in avr.c
+ is needed to expand the built-in, use `nothing'.
