<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>
|
|
<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.
