<h4 class="subsection">6.59.31 TILE-Gx Built-in Functions</h4>
|
|
|
|
<p>GCC provides intrinsics to access every instruction of the TILE-Gx
|
|
processor. The intrinsics are of the form:
|
|
</p>
|
|
<div class="smallexample">
|
|
<pre class="smallexample">
|
|
|
|
unsigned long long __insn_<var>op</var> (...)
|
|
|
|
</pre></div>
|
|
|
|
<p>Where <var>op</var> is the name of the instruction. Refer to the ISA manual
|
|
for the complete list of instructions.
|
|
</p>
|
|
<p>GCC also provides intrinsics to directly access the network registers.
|
|
The intrinsics are:
|
|
</p>
|
|
<div class="smallexample">
|
|
<pre class="smallexample">
|
|
|
|
unsigned long long __tile_idn0_receive (void)
|
|
unsigned long long __tile_idn1_receive (void)
|
|
unsigned long long __tile_udn0_receive (void)
|
|
unsigned long long __tile_udn1_receive (void)
|
|
unsigned long long __tile_udn2_receive (void)
|
|
unsigned long long __tile_udn3_receive (void)
|
|
void __tile_idn_send (unsigned long long)
|
|
void __tile_udn_send (unsigned long long)
|
|
|
|
</pre></div>
|
|
|
|
<p>The intrinsic <code>void __tile_network_barrier (void)</code> is used to
|
|
guarantee that no network operations before it are reordered with
|
|
those after it.
