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-710"></a><a name="index-pseudo_002dop-_002edword_002c-CRIS-711"></a><a name="index-CRIS-assembler-directive-_002edword-712"></a><a name="index-CRIS-pseudo_002dop-_002edword-713"></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-714"></a><a name="index-pseudo_002dop-_002esyntax_002c-CRIS-715"></a><a name="index-CRIS-assembler-directive-_002esyntax-716"></a><a name="index-CRIS-pseudo_002dop-_002esyntax-717"></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 <span class="samp">$</span> character prefix on all registers optional. It overrides a previous setting, including the corresponding effect of the option <span class="option">--no-underscore</span>. If this directive is used when ordinary symbols do not have a <span class="samp">_</span> character prefix, care must be taken to avoid ambiguities whether an operand is a register or a symbol; using symbols with names the same as general or special registers then invoke undefined behavior. <br><dt><code>register_prefix</code><dd> This directive makes a <span class="samp">$</span> character prefix on all registers mandatory. It overrides a previous setting, including the corresponding effect of the option <span class="option">--underscore</span>. <br><dt><code>leading_underscore</code><dd> This is an assertion directive, emitting an error if the <span class="option">--no-underscore</span> 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 <span class="option">--underscore</span> is in effect. </dl> <br><dt><code>.arch ARGUMENT</code><dd><a name="index-assembler-directive-_002earch_002c-CRIS-718"></a><a name="index-pseudo_002dop-_002earch_002c-CRIS-719"></a><a name="index-CRIS-assembler-directive-_002earch-720"></a><a name="index-CRIS-pseudo_002dop-_002earch-721"></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 <span class="option">--march=</span><var>architecture</var> 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.
