#### 6.56.23 TILEPro Built-in Functions

GCC provides intrinsics to access every instruction of the TILEPro processor. The intrinsics are of the form:

         unsigned __insn_op (...)

where op is the name of the instruction. Refer to the ISA manual for the complete list of instructions.

GCC also provides intrinsics to directly access the network registers. The intrinsics are:

         unsigned __tile_idn0_receive (void)
         unsigned __tile_idn1_receive (void)
         unsigned __tile_sn_receive (void)
         unsigned __tile_udn0_receive (void)
         unsigned __tile_udn1_receive (void)
         unsigned __tile_udn2_receive (void)
         unsigned __tile_udn3_receive (void)
         void __tile_idn_send (unsigned)
         void __tile_sn_send (unsigned)
         void __tile_udn_send (unsigned)

The intrinsic `void __tile_network_barrier (void)` is used to guarantee that no network operations before it are reordered with those after it.
