<h5 class="subsubsection">9.7.4.4 Assembler Directives</h5>

<p><a name="index-assembler-directives_002c-CRIS-733"></a><a name="index-pseudo_002dops_002c-CRIS-734"></a><a name="index-CRIS-assembler-directives-735"></a><a name="index-CRIS-pseudo_002dops-736"></a>
There are a few CRIS-specific pseudo-directives in addition to
the generic ones.  See <a href="Pseudo-Ops.html#Pseudo-Ops">Pseudo Ops</a>.  Constants emitted by
pseudo-directives are in little-endian order for CRIS.  There is
no support for floating-point-specific directives for CRIS.

     <dl>
<dt><code>.dword EXPRESSIONS</code><dd><a name="index-assembler-directive-_002edword_002c-CRIS-737"></a><a name="index-pseudo_002dop-_002edword_002c-CRIS-738"></a><a name="index-CRIS-assembler-directive-_002edword-739"></a><a name="index-CRIS-pseudo_002dop-_002edword-740"></a>
The <code>.dword</code> directive is a synonym for <code>.int</code>,
expecting zero or more EXPRESSIONS, separated by commas.  For
each expression, a 32-bit little-endian constant is emitted.

     <br><dt><code>.syntax ARGUMENT</code><dd><a name="index-assembler-directive-_002esyntax_002c-CRIS-741"></a><a name="index-pseudo_002dop-_002esyntax_002c-CRIS-742"></a><a name="index-CRIS-assembler-directive-_002esyntax-743"></a><a name="index-CRIS-pseudo_002dop-_002esyntax-744"></a>The <code>.syntax</code> directive takes as <var>ARGUMENT</var> one of the
following case-sensitive choices.

          <dl>
<dt><code>no_register_prefix</code><dd>
The <code>.syntax no_register_prefix</code> <a name="crisnous"></a>directive
makes a &lsquo;<samp><span class="samp">$</span></samp>&rsquo; character prefix on all registers optional.  It
overrides a previous setting, including the corresponding effect
of the option <samp><span class="option">--no-underscore</span></samp>.  If this directive is
used when ordinary symbols do not have a &lsquo;<samp><span class="samp">_</span></samp>&rsquo; character
prefix, care must be taken to avoid ambiguities whether an
operand is a register or a symbol; using symbols with names the
same as general or special registers then invoke undefined
behavior.

          <br><dt><code>register_prefix</code><dd>
This directive makes a &lsquo;<samp><span class="samp">$</span></samp>&rsquo; character prefix on all
registers mandatory.  It overrides a previous setting, including
the corresponding effect of the option <samp><span class="option">--underscore</span></samp>.

          <br><dt><code>leading_underscore</code><dd>
This is an assertion directive, emitting an error if the
<samp><span class="option">--no-underscore</span></samp> option is in effect.

          <br><dt><code>no_leading_underscore</code><dd>
This is the opposite of the <code>.syntax leading_underscore</code>
directive and emits an error if the option <samp><span class="option">--underscore</span></samp>
is in effect. 
</dl>

     <br><dt><code>.arch ARGUMENT</code><dd><a name="index-assembler-directive-_002earch_002c-CRIS-745"></a><a name="index-pseudo_002dop-_002earch_002c-CRIS-746"></a><a name="index-CRIS-assembler-directive-_002earch-747"></a><a name="index-CRIS-pseudo_002dop-_002earch-748"></a>This is an assertion directive, giving an error if the specified
<var>ARGUMENT</var> is not the same as the specified or default value
for the <samp><span class="option">--march=</span><var>architecture</var></samp> option
(see <a href="march_002doption.html#march_002doption">march-option</a>).

     <!-- If you compare with md_pseudo_table, you see that we don't -->
     <!-- document ".file" and ".loc" here.  This is because we're just -->
     <!-- wrapping the corresponding ELF function and emitting an error for -->
     <!-- a.out. -->
   </dl>
