<h4 class="section">SH64 Machine Directives</h4>



   <p>In addition to the SH directives, the SH64 provides the following

directives:



     <dl>



     <br><dt><code>.mode [shmedia|shcompact]</code>

     <dd><dt><code>.isa [shmedia|shcompact]</code>

     <dd>Specify the ISA for the following instructions (the two directives are

equivalent).  Note that programs such as <code>objdump</code> rely on symbolic

labels to determine when such mode switches occur (by checking the least

significant bit of the label's address), so such mode/isa changes should

always be followed by a label (in practice, this is true anyway).  Note

that you cannot use these directives if you didn't specify an ISA on the

command line.



     <br><dt><code>.abi [32|64]</code>

     <dd>Specify the ABI for the following instructions.  Note that you cannot use

this directive unless you specified an ABI on the command line, and the

ABIs specified must match.



     <br><dt><code>.uaquad</code>

     <dd>Like .uaword and .ualong, this allows you to specify an intenionally

unaligned quadword (64 bit word).
