  32 /* To use this file we need to define one of the following:
  33    QQ_MODE, UQQ_MODE, HQ_MODE, UHQ_MODE, SQ_MODE, USQ_MODE, DQ_MODE, UDQ_MODE,
  34    TQ_MODE, UTQ_MODE, HA_MODE, UHA_MODE, SA_MODE, USA_MODE, DA_MODE, UDA_MODE,
  35    TA_MODE, UTA_MODE.
  36    Then, all operators for this machine mode will be created.
  37
  38    Or, we need to define FROM_* TO_* for conversions from one mode to another
  39    mode.  The mode could be one of the following:
  40    Fract: QQ, UQQ, HQ, UHQ, SQ, USQ, DQ, UDQ, TQ, UTQ
  41    Accum: HA, UHA, SA, USA, DA, UDA, TA, UTA
  42    Signed integer: QI, HI, SI, DI, TI
  43    Unsigned integer: UQI, UHI, USI, UDI, UTI
  44    Floating-point: SF, DF
  45    Ex: If we define FROM_QQ and TO_SI, the conversion from QQ to SI is
  46    generated.  */
