| <h4 class="subsection">6.52.4 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: |
| |
| <pre class="smallexample"> void __builtin_bfin_csync (void) |
| void __builtin_bfin_ssync (void) |
| </pre> |
| </body></html> |
