<h4 class="subsection">6.31.13 m68k Function Attributes</h4>
|
||
|
|
|
||
|
|
<p>These function attributes are supported by the m68k back end:
|
||
|
|
</p>
|
||
|
|
<dl compact="compact">
|
||
|
|
<dt><code>interrupt</code></dt>
|
||
|
|
<dt><code>interrupt_handler</code></dt>
|
||
|
|
<dd><a name="index-interrupt-function-attribute_002c-m68k"></a>
|
||
|
|
<a name="index-interrupt_005fhandler-function-attribute_002c-m68k"></a>
|
||
|
|
<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. Either name may be used.
|
||
|
|
</p>
|
||
|
|
</dd>
|
||
|
|
<dt><code>interrupt_thread</code></dt>
|
||
|
|
<dd><a name="index-interrupt_005fthread-function-attribute_002c-fido"></a>
|
||
|
|
<p>Use this attribute on fido, a subarchitecture of the m68k, to indicate
|
||
|
|
that the specified function is an interrupt handler that is designed
|
||
|
|
to run as a thread. The compiler omits generate prologue/epilogue
|
||
|
|
sequences and replaces the return instruction with a <code>sleep</code>
|
||
|
|
instruction. This attribute is available only on fido.
