| <a name="index-CRIS-assembler-directives"></a> |
| <a name="index-CRIS-pseudo_002dops"></a> |
| |
| <p>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. |
| </p> |
| <dl compact="compact"> |
| <dt><code>.dword EXPRESSIONS</code></dt> |
| <dd><a name="index-assembler-directive-_002edword_002c-CRIS"></a> |
| <a name="index-pseudo_002dop-_002edword_002c-CRIS"></a> |
| <a name="index-CRIS-assembler-directive-_002edword"></a> |
| <a name="index-CRIS-pseudo_002dop-_002edword"></a> |
| |
| <p>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. |
| </p> |
| </dd> |
| <dt><code>.syntax ARGUMENT</code></dt> |
| <dd><a name="index-assembler-directive-_002esyntax_002c-CRIS"></a> |
| <a name="index-pseudo_002dop-_002esyntax_002c-CRIS"></a> |
| <a name="index-CRIS-assembler-directive-_002esyntax"></a> |
| <a name="index-CRIS-pseudo_002dop-_002esyntax"></a> |
| <p>The <code>.syntax</code> directive takes as <var>ARGUMENT</var> one of the |
| following case-sensitive choices. |
| </p> |
| <dl compact="compact"> |
| <dt><code>no_register_prefix</code></dt> |
| <dd> |
| <p>The <code>.syntax no_register_prefix</code> <a name="crisnous"></a>directive |
| makes a ‘<samp>$</samp>’ character prefix on all registers optional. It |
| overrides a previous setting, including the corresponding effect |
| of the option <samp>--no-underscore</samp>. If this directive is |
| used when ordinary symbols do not have a ‘<samp>_</samp>’ character |
| prefix, care must be taken to avoid ambiguities whether an |
| operand is a register or a symbol; using symbols with names the |
| same as general or special registers then invoke undefined |
| behavior. |
| </p> |
| </dd> |
| <dt><code>register_prefix</code></dt> |
| <dd> |
| <p>This directive makes a ‘<samp>$</samp>’ character prefix on all |
| registers mandatory. It overrides a previous setting, including |
| the corresponding effect of the option <samp>--underscore</samp>. |
| </p> |
| </dd> |
| <dt><code>leading_underscore</code></dt> |
| <dd> |
| <p>This is an assertion directive, emitting an error if the |
| <samp>--no-underscore</samp> option is in effect. |
| </p> |
| </dd> |
| <dt><code>no_leading_underscore</code></dt> |
| <dd> |
| <p>This is the opposite of the <code>.syntax leading_underscore</code> |
| directive and emits an error if the option <samp>--underscore</samp> |
| is in effect. |
| </p></dd> |
| </dl> |
| |
| </dd> |
| <dt><code>.arch ARGUMENT</code></dt> |

| <a name="index-CRIS-assembler-directive-_002earch"></a> |
| <a name="index-CRIS-pseudo_002dop-_002earch"></a> |
| <p>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>--march=<var>architecture</var></samp> option |
| (see <a href="CRIS_002dOpts.html#march_002doption">march-option</a>). |
