+
+ * genmodes.c (struct mode_data): Add need_bytesize_adj field.
+ (blank_mode): Initialize it.
+ (emit_mode_size_inline, emit_mode_nunits_inline,
+ emit_mode_inner_inline): New functions.
+ (emit_insn_modes_h): Call them and surround their output with
+ #if GCC_VERSION >= 4001 ... #endif.
+ * machmode.h (GET_MODE_SIZE, GET_MODE_NUNITS, GET_MODE_INNER):
+ For GCC_VERSION >= 4001 use mode_*_inline routines instead of
+ mode_* arrays if the argument is __builtin_constant_p.
+ * lower-subreg.c (dump_choices): Make sure GET_MODE_SIZE argument
+ is enum machine_mode.
