<h4 class="subsection">9.35.2 Enforcing aligned data</h4>

<p><a name="index-data-alignment-on-SPARC-1633"></a><a name="index-SPARC-data-alignment-1634"></a>SPARC GAS normally permits data to be misaligned.  For example, it
permits the <code>.long</code> pseudo-op to be used on a byte boundary. 
However, the native SunOS assemblers issue an error when they see
misaligned data.

   <p><a name="index-g_t_002d_002denforce_002daligned_002ddata-1635"></a>You can use the <code>--enforce-aligned-data</code> option to make SPARC GAS
also issue an error about misaligned data, just as the SunOS
assemblers do.

   <p>The <code>--enforce-aligned-data</code> option is not the default because gcc
issues misaligned data pseudo-ops when it initializes certain packed
data structures (structures defined using the <code>packed</code> attribute). 
You may have to assemble with GAS in order to initialize packed data
structures in your own code.
