GCC provides intrinsics to access certain instructions of the TI C6X
processors. These intrinsics, listed below, are available after
inclusion of the c6x_intrinsics.h header file. They map directly
to C6X instructions.
int _sadd (int, int)
int _ssub (int, int)
int _sadd2 (int, int)
int _ssub2 (int, int)
long long _mpy2 (int, int)
long long _smpy2 (int, int)
int _add4 (int, int)
int _sub4 (int, int)
int _saddu4 (int, int)
int _smpy (int, int)
int _smpyh (int, int)
int _smpyhl (int, int)
int _smpylh (int, int)
int _sshl (int, int)
int _subc (int, int)
int _avg2 (int, int)
int _avgu4 (int, int)
int _clrr (int, int)
int _extr (int, int)
