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