These are used for generating <code class="code">CSYNC</code> and <code class="code">SSYNC</code> machine insns without using inline assembly; by using these built-in functions the compiler can automatically add workarounds for hardware errata involving these instructions. These functions are named as follows: </p> <div class="example smallexample"> <pre class="example-preformatted" data-language="cpp">void __builtin_bfin_csync (void);
void __builtin_bfin_ssync (void);</pre>
