A future PowerPC processor may provide Dense Math Facility (DMF)
instructions. GCC provides support for these instructions through the
following built-in functions which are enabled with the -mdense-math
option. The vec_t type below is defined to be a normal vector unsigned char
type. The __dmr1024 type is a 1024 bit integer type.
The built-in functions supported are:
void __builtin_dmsetdmrz (__dmr1024 *); void __builtin_dmmr (__dmr1024 *, __dmr1024 *); void __builtin_dmxor (__dmr1024 *, __dmr1024 *); void __builtin_build_dmr (__dmr1024 *, vec_t, vec_t, vec_t, vec_t, vec_t, vec_t, vec_t, vec_t);
