+
+<p>These function attributes are supported by the NDS32 back end:
+</p>
+<dl compact="compact">
+<dd><a name="index-exception-function-attribute"></a>
+<a name="index-exception-handler-functions_002c-NDS32"></a>
+</dd>
+<dt><code>exception</code></dt>
+<dd><p>Use this attribute on the NDS32 target to indicate that the specified function
+is an exception handler.  The compiler will generate corresponding sections
+for use in an exception handler.
+</p>
+<a name="index-interrupt-function-attribute_002c-NDS32"></a>
+</dd>
+<dt><code>interrupt</code></dt>
+<dd><p>On NDS32 target, this attribute indicates that the specified function
+is an interrupt handler.  The compiler generates corresponding sections
+for use in an interrupt handler.  You can use the following attributes
+to modify the behavior:
+</p><dl compact="compact">
+<dd><a name="index-nested-function-attribute_002c-NDS32"></a>
+</dd>
+<dt><code>nested</code></dt>
+<dd><p>This interrupt service routine is interruptible.
+<a name="index-not_005fnested-function-attribute_002c-NDS32"></a>
+</p></dd>
+<dt><code>not_nested</code></dt>
+<dd><p>This interrupt service routine is not interruptible.
+<a name="index-nested_005fready-function-attribute_002c-NDS32"></a>
+</p></dd>
+<dt><code>nested_ready</code></dt>
+<dd><p>This interrupt service routine is interruptible after <code>PSW.GIE</code>
+(global interrupt enable) is set.  This allows interrupt service routine to
+finish some short critical code before enabling interrupts.
+<a name="index-save_005fall-function-attribute_002c-NDS32"></a>
+</p></dd>
+<dt><code>save_all</code></dt>
+<dd><p>The system will help save all registers into stack before entering
+interrupt handler.
+<a name="index-partial_005fsave-function-attribute_002c-NDS32"></a>
+</p></dd>
+<dt><code>partial_save</code></dt>
+<dd><p>The system will help save caller registers into stack before entering
+interrupt handler.
+</p></dd>
+</dl>
+
+<a name="index-naked-function-attribute_002c-NDS32"></a>
+</dd>
+<dt><code>naked</code></dt>
+<dd><p>This attribute allows the compiler to construct the
+requisite function declaration, while allowing the body of the
+function to be assembly code. The specified function will not have
+prologue/epilogue sequences generated by the compiler. Only basic
+<code>asm</code> statements can safely be included in naked functions
+(see <a href="Basic-Asm.html#Basic-Asm">Basic Asm</a>). While using extended <code>asm</code> or a mixture of
+basic <code>asm</code> and C code may appear to work, they cannot be
+depended upon to work reliably and are not supported.
+</p>
+<a name="index-reset-function-attribute_002c-NDS32"></a>
+<a name="index-reset-handler-functions"></a>
+</dd>
+<dt><code>reset</code></dt>
+<dd><p>Use this attribute on the NDS32 target to indicate that the specified function
+is a reset handler.  The compiler will generate corresponding sections
+for use in a reset handler.  You can use the following attributes
+to provide extra exception handling:
+</p><dl compact="compact">
+<dd><a name="index-nmi-function-attribute_002c-NDS32"></a>
+</dd>
+<dt><code>nmi</code></dt>
+<dd><p>Provide a user-defined function to handle NMI exception.
+<a name="index-warm-function-attribute_002c-NDS32"></a>
+</p></dd>
+<dt><code>warm</code></dt>
+<dd><p>Provide a user-defined function to handle warm reset exception.
