   <p>For detailed information on the SH64 machine instruction set, see

<cite>SuperH 64 bit RISC Series Architecture Manual</cite> (SuperH, Inc.).



   <p><code>as</code> implements all the standard SH64 opcodes.  In

addition, the following pseudo-opcodes may be expanded into one or more

alternate opcodes:



     <dl>



     <br><dt><code>movi</code>

     <dd>If the value doesn't fit into a standard <code>movi</code> opcode,

<code>as</code> will replace the <code>movi</code> with a sequence of

<code>movi</code> and <code>shori</code> opcodes.



     <br><dt><code>pt</code>

     <dd>This expands to a sequence of <code>movi</code> and <code>shori</code> opcode,

followed by a <code>ptrel</code> opcode, or to a <code>pta</code> or <code>ptb</code>

opcode, depending on the label referenced.
