<h4 class="section">Enforcing aligned data</h4>



   <p>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 and Solaris assemblers issue an error when

they see misaligned data.



   <p>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 and Solaris

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.
