<h4 class="subsection">6.60.11 Blackfin Built-in Functions</h4>

<p>Currently, there are two Blackfin-specific built-in functions.  These are
used for generating <code>CSYNC</code> and <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:
