+<h4 class="subsection">6.33.7 Blackfin Function Attributes</h4>
+
+<p>These function attributes are supported by the Blackfin back end:
+</p>
+<dl compact="compact">
+<dd>
+<a name="index-exception_005fhandler-function-attribute"></a>
+<a name="index-exception-handler-functions_002c-Blackfin"></a>
+</dd>
+<dt><code>exception_handler</code></dt>
+<dd><p>Use this attribute on the Blackfin to indicate that the specified function
+is an exception handler.  The compiler generates function entry and
+exit sequences suitable for use in an exception handler when this
+attribute is present.
+</p>
+<a name="index-interrupt_005fhandler-function-attribute_002c-Blackfin"></a>
+</dd>
+<dt><code>interrupt_handler</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.
+</p>
+<a name="index-kspisusp-function-attribute_002c-Blackfin"></a>
+<a name="index-User-stack-pointer-in-interrupts-on-the-Blackfin"></a>
+</dd>
+<dt><code>kspisusp</code></dt>
+<dd><p>When used together with <code>interrupt_handler</code>, <code>exception_handler</code>
+or <code>nmi_handler</code>, code is generated to load the stack pointer
+from the USP register in the function prologue.
+</p>
+<a name="index-l1_005ftext-function-attribute_002c-Blackfin"></a>
+</dd>
+<dt><code>l1_text</code></dt>
+<dd><p>This attribute specifies a function to be placed into L1 Instruction
+SRAM. The function is put into a specific section named <code>.l1.text</code>.
+With <samp>-mfdpic</samp>, function calls with a such function as the callee
+or caller uses inlined PLT.
+</p>
+<a name="index-l2-function-attribute_002c-Blackfin"></a>
+</dd>
+<dt><code>l2</code></dt>
+<dd><p>This attribute specifies a function to be placed into L2
+SRAM. The function is put into a specific section named
+<code>.l2.text</code>. With <samp>-mfdpic</samp>, callers of such functions use
+an inlined PLT.
+</p>
+<a name="index-indirect-calls_002c-Blackfin"></a>
+<a name="index-longcall-function-attribute_002c-Blackfin"></a>
+<a name="index-shortcall-function-attribute_002c-Blackfin"></a>
+</dd>
+<dt><code>longcall</code></dt>
+<dt><code>shortcall</code></dt>
+<dd><p>The <code>longcall</code> attribute
+indicates that the function might be far away from the call site and
+require a different (more expensive) calling sequence.  The
+<code>shortcall</code> attribute indicates that the function is always close
+enough for the shorter calling sequence to be used.  These attributes
+override the <samp>-mlongcall</samp> switch.
+</p>
+<a name="index-nesting-function-attribute_002c-Blackfin"></a>
+<a name="index-Allow-nesting-in-an-interrupt-handler-on-the-Blackfin-processor"></a>
+</dd>
+<dt><code>nesting</code></dt>
+<dd><p>Use this attribute together with <code>interrupt_handler</code>,
+<code>exception_handler</code> or <code>nmi_handler</code> to indicate that the function
+entry code should enable nested interrupts or exceptions.
+</p>
+<a name="index-nmi_005fhandler-function-attribute_002c-Blackfin"></a>
+<a name="index-NMI-handler-functions-on-the-Blackfin-processor"></a>
+</dd>
+<dt><code>nmi_handler</code></dt>
+<dd><p>Use this attribute on the Blackfin to indicate that the specified function
+is an NMI handler.  The compiler generates function entry and
+exit sequences suitable for use in an NMI handler when this
+attribute is present.
+</p>
+<a name="index-saveall-function-attribute_002c-Blackfin"></a>
+<a name="index-save-all-registers-on-the-Blackfin"></a>
+</dd>
+<dt><code>saveall</code></dt>
+<dd><p>Use this attribute to indicate that
+all registers except the stack pointer should be saved in the prologue
+regardless of whether they are used or not.
+</p></dd>
