+<h4 class="subsection">6.33.10 Epiphany Function Attributes</h4>
+
+<p>These function attributes are supported by the Epiphany back end:
+</p>
+<dl compact="compact">
+<dd><a name="index-disinterrupt-function-attribute_002c-Epiphany"></a>
+</dd>
+<dt><code>disinterrupt</code></dt>
+<dd><p>This attribute causes the compiler to emit
+instructions to disable interrupts for the duration of the given
+function.
+</p>
+<a name="index-forwarder_005fsection-function-attribute_002c-Epiphany"></a>
+</dd>
+<dt><code>forwarder_section</code></dt>
+<dd><p>This attribute modifies the behavior of an interrupt handler.
+The interrupt handler may be in external memory which cannot be
+reached by a branch instruction, so generate a local memory trampoline
+to transfer control.  The single parameter identifies the section where
+the trampoline is placed.
+</p>
+<a name="index-interrupt-function-attribute_002c-Epiphany"></a>
+</dd>
+<dt><code>interrupt</code></dt>
+<dd><p>Use this attribute to indicate
+that the specified function is an interrupt handler.  The compiler generates
+function entry and exit sequences suitable for use in an interrupt handler
+when this attribute is present.  It may also generate
+a special section with code to initialize the interrupt vector table.
+</p>
+<p>On Epiphany targets one or more optional parameters can be added like this:
+</p>
+<div class="smallexample">
+<pre class="smallexample">void __attribute__ ((interrupt (&quot;dma0, dma1&quot;))) universal_dma_handler ();
+</pre></div>
+
+<p>Permissible values for these parameters are: <code>reset</code><!-- /@w -->,
+<code><span class="nolinebreak">software_exception</span></code><!-- /@w -->, <code><span class="nolinebreak">page_miss</span></code><!-- /@w -->,
+<code>timer0</code><!-- /@w -->, <code>timer1</code><!-- /@w -->, <code>message</code><!-- /@w -->,
+<code>dma0</code><!-- /@w -->, <code>dma1</code><!-- /@w -->, <code>wand</code><!-- /@w --> and <code>swi</code><!-- /@w -->.
+Multiple parameters indicate that multiple entries in the interrupt
+vector table should be initialized for this function, i.e. for each
+parameter <var>name</var><!-- /@w -->, a jump to the function is emitted in
+the section <span class="nolinebreak">ivt_entry_</span><var>name</var><!-- /@w -->.  The parameter(s) may be omitted
+entirely, in which case no interrupt vector table entry is provided.
+</p>
+<p>Note that interrupts are enabled inside the function
+unless the <code>disinterrupt</code> attribute is also specified.
+</p>
+<p>The following examples are all valid uses of these attributes on
+Epiphany targets:
+</p><div class="smallexample">
+<pre class="smallexample">void __attribute__ ((interrupt)) universal_handler ();
+void __attribute__ ((interrupt (&quot;dma1&quot;))) dma1_handler ();
+void __attribute__ ((interrupt (&quot;dma0, dma1&quot;))) 
+  universal_dma_handler ();
+void __attribute__ ((interrupt (&quot;timer0&quot;), disinterrupt))
+  fast_timer_handler ();
+void __attribute__ ((interrupt (&quot;dma0, dma1&quot;), 
+                     forwarder_section (&quot;tramp&quot;)))
+  external_dma_handler ();
+</pre></div>
+
+<a name="index-long_005fcall-function-attribute_002c-Epiphany"></a>
+<a name="index-short_005fcall-function-attribute_002c-Epiphany"></a>
+<a name="index-indirect-calls_002c-Epiphany"></a>
+</dd>
+<dt><code>long_call</code></dt>
+<dt><code>short_call</code></dt>
+<dd><p>These attributes specify how a particular function is called.
+These attributes override the
+<samp>-mlong-calls</samp> (see <a href="Adapteva-Epiphany-Options.html#Adapteva-Epiphany-Options">Adapteva Epiphany Options</a>)
+command-line switch and <code>#pragma long_calls</code> settings.
+</p></dd>
