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. */ /* Permit the tm.h file to select the endianness to use just for this file.
