<h4 class="subsection">9.21.5 680x0 Machine Directives</h4>

<p><a name="index-M680x0-directives-1177"></a><a name="index-directives_002c-M680x0-1178"></a>In order to be compatible with the Sun assembler the 680x0 assembler
understands the following directives.

     
<a name="index-g_t_0040code_007bdata1_007d-directive_002c-M680x0-1179"></a>
<dl><dt><code>.data1</code><dd>This directive is identical to a <code>.data 1</code> directive.

     <p><a name="index-g_t_0040code_007bdata2_007d-directive_002c-M680x0-1180"></a><br><dt><code>.data2</code><dd>This directive is identical to a <code>.data 2</code> directive.

     <p><a name="index-g_t_0040code_007beven_007d-directive_002c-M680x0-1181"></a><br><dt><code>.even</code><dd>This directive is a special case of the <code>.align</code> directive; it
aligns the output to an even byte boundary.

     <p><a name="index-g_t_0040code_007bskip_007d-directive_002c-M680x0-1182"></a><br><dt><code>.skip</code><dd>This directive is identical to a <code>.space</code> directive.

     <p><a name="index-g_t_0040code_007barch_007d-directive_002c-M680x0-1183"></a><br><dt><code>.arch </code><var>name</var><dd>Select the target architecture and extension features.  Valid values
for <var>name</var> are the same as for the <samp><span class="option">-march</span></samp> command line
option.  This directive cannot be specified after
any instructions have been assembled.  If it is given multiple times,
or in conjunction with the <samp><span class="option">-march</span></samp> option, all uses must be for
the same architecture and extension set.

     <p><a name="index-g_t_0040code_007bcpu_007d-directive_002c-M680x0-1184"></a><br><dt><code>.cpu </code><var>name</var><dd>Select the target cpu.  Valid valuse
for <var>name</var> are the same as for the <samp><span class="option">-mcpu</span></samp> command line
option.  This directive cannot be specified after
any instructions have been assembled.  If it is given multiple times,
or in conjunction with the <samp><span class="option">-mopt</span></samp> option, all uses must be for
the same cpu.
