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. */ | |
