6.65.37 TI C6X Built-in Functions ¶

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);
