+ TQ_MODE, UTQ_MODE, HA_MODE, UHA_MODE, SA_MODE, USA_MODE, DA_MODE, UDA_MODE,
+ TA_MODE, UTA_MODE.
+ Then, all operators for this machine mode will be created.
+
+ Or, we need to define FROM_* TO_* for conversions from one mode to another
+ mode. The mode could be one of the following:
+ Fract: QQ, UQQ, HQ, UHQ, SQ, USQ, DQ, UDQ, TQ, UTQ
+ Accum: HA, UHA, SA, USA, DA, UDA, TA, UTA
+ Signed integer: QI, HI, SI, DI, TI
+ Unsigned integer: UQI, UHI, USI, UDI, UTI
+ Floating-point: SF, DF
+ Ex: If we define FROM_QQ and TO_SI, the conversion from QQ to SI is
+ generated. */
