/* 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. */ |
