  68. <h4 class="subsection">6.33.18 MeP Function Attributes</h4>
  69. <p>These function attributes are supported by the MeP back end:
  70. </p>
  71. <dl compact="compact">
  72. <dt><code>disinterrupt</code></dt>
  73. <dd><a name="index-disinterrupt-function-attribute_002c-MeP"></a>
  74. <p>On MeP targets, this attribute causes the compiler to emit
  75. instructions to disable interrupts for the duration of the given
  76. function.
  77. </p>
  78. </dd>
  79. <dt><code>interrupt</code></dt>
  80. <dd><a name="index-interrupt-function-attribute_002c-MeP"></a>
  81. <p>Use this attribute to indicate
  82. that the specified function is an interrupt handler. The compiler generates
  83. function entry and exit sequences suitable for use in an interrupt handler
  84. when this attribute is present.
  85. </p>
  86. </dd>
  87. <dt><code>near</code></dt>
  88. <dd><a name="index-near-function-attribute_002c-MeP"></a>
  89. <p>This attribute causes the compiler to assume the called
  90. function is close enough to use the normal calling convention,
  91. overriding the <samp>-mtf</samp> command-line option.
  92. </p>
  93. </dd>
  94. <dt><code>far</code></dt>
  95. <dd><a name="index-far-function-attribute_002c-MeP"></a>
  96. <p>On MeP targets this causes the compiler to use a calling convention
  97. that assumes the called function is too far away for the built-in
  98. addressing modes.
  99. </p>
  100. </dd>
  101. <dt><code>vliw</code></dt>
  102. <dd><a name="index-vliw-function-attribute_002c-MeP"></a>
  103. <p>The <code>vliw</code> attribute tells the compiler to emit
  104. instructions in VLIW mode instead of core mode. Note that this
  105. attribute is not allowed unless a VLIW coprocessor has been configured
  106. and enabled through command-line options.
  107. </p></dd>
