/* To use this file we need to define one of the following:
|
||
|
|
QQ_MODE, UQQ_MODE, HQ_MODE, UHQ_MODE, SQ_MODE, USQ_MODE, DQ_MODE, UDQ_MODE,
|
||
|
|
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. */
