<h4 class="subsection">6.31.15 MeP Function Attributes</h4>
|
||
|
|
|
||
|
|
<p>These function attributes are supported by the MeP back end:
|
||
|
|
</p>
|
||
|
|
<dl compact="compact">
|
||
|
|
<dt><code>disinterrupt</code></dt>
|
||
|
|
<dd><a name="index-disinterrupt-function-attribute_002c-MeP"></a>
|
||
|
|
<p>On MeP targets, this attribute causes the compiler to emit
|
||
|
|
instructions to disable interrupts for the duration of the given
|
||
|
|
function.
|
||
|
|
</p>
|
||
|
|
</dd>
|
||
|
|
<dt><code>interrupt</code></dt>
|
||
|
|
<dd><a name="index-interrupt-function-attribute_002c-MeP"></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.
|
||
|
|
</p>
|
||
|
|
</dd>
|
||
|
|
<dt><code>near</code></dt>
|
||
|
|
<dd><a name="index-near-function-attribute_002c-MeP"></a>
|
||
|
|
<p>This attribute causes the compiler to assume the called
|
||
|
|
function is close enough to use the normal calling convention,
|
||
|
|
overriding the <samp>-mtf</samp> command-line option.
|
||
|
|
</p>
|
||
|
|
</dd>
|
||
|
|
<dt><code>far</code></dt>
|
||
|
|
<dd><a name="index-far-function-attribute_002c-MeP"></a>
|
||
|
|
<p>On MeP targets this causes the compiler to use a calling convention
|
||
|
|
that assumes the called function is too far away for the built-in
|
||
|
|
addressing modes.
|
||
|
|
</p>
|
||
|
|
</dd>
|
||
|
|
<dt><code>vliw</code></dt>
|
||
|
|
<dd><a name="index-vliw-function-attribute_002c-MeP"></a>
|
||
|
|
<p>The <code>vliw</code> attribute tells the compiler to emit
|
||
|
|
instructions in VLIW mode instead of core mode. Note that this
|
||
|
|
attribute is not allowed unless a VLIW coprocessor has been configured
|
||
|
|
and enabled through command-line options.
