- <h4 class="subsection">6.33.18 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.
- </p></dd>
