Would this be sort of a bug? It is used as follows. #if LONG_LONG_TYPE_SIZE > 32 /* These typedefs are usually forbidden on archs with UNITS_PER_WORD 2 */ typedef int DItype __attribute__ ((mode (DI))); typedef unsigned int UDItype __attribute__ ((mode (DI))); #if MIN_UNITS_PER_WORD > 4 /* These typedefs are usually forbidden on archs with UNITS_PER_WORD 4 */ typedef int TItype __attribute__ ((mode (TI))); typedef unsigned int UTItype __attribute__ ((mode (TI))); #endif #endif What would be a good way to prevent gcc from generating DI stuff for targets that do not support them? Thanks, Kazu Hirata
