+<p>Use this attribute to indicate that the function is an interrupt handler. All volatile registers (in addition to non-volatile registers) are saved in the function prologue. If the function is a leaf function, only volatiles used by the function are saved. A normal function return is generated instead of a return from interrupt. </p> </dd> <dt>

+<p>Use this attribute to indicate that the specified function is a break handler. The compiler generates function entry and exit sequences suitable for use in an break handler when this attribute is present. The return from <code class="code">break_handler</code> is done through the <code class="code">rtbd</code> instead of <code class="code">rtsd</code>. </p> <div class="example smallexample"> <pre class="example-preformatted" data-language="cpp">void f () __attribute__ ((break_handler));</pre>

+</dt> <dt><code class="code">fast_interrupt</code></dt> <dd><p>These attributes indicate that the specified function is an interrupt handler. Use the <code class="code">fast_interrupt</code> attribute to indicate handlers used in low-latency interrupt mode, and <code class="code">interrupt_handler</code> for interrupts that do not use low-latency handlers. In both cases, GCC emits appropriate prologue code and generates a return from the handler using <code class="code">rtid</code> instead of <code class="code">rtsd</code>. </p></dd> </dl> </div><div class="_attribution">
