<h4 class="subsection">9.24.1 S12Z Options</h4>
|

|
<a name="index-options_002c-S12Z"></a>
|
|
<a name="index-S12Z-options"></a>
|
|
|
|
<p>The S12Z version of <code>as</code> recognizes the following options:
|
|
</p>
|
|
<dl compact="compact">
|
|
<dt>‘<samp>-mreg-prefix=<var>prefix</var></samp>’</dt>
|
|
<dd><a name="index-_002dmreg_002dprefix_003dprefix-option_002c-reg_002dprefix"></a>
|
|
<p>You can use the ‘<samp>-mreg-prefix=<var>pfx</var></samp>’ option to indicate
|
|
that the assembler should expect all register names to be prefixed with the
|
|
string <var>pfx</var>.
|
|
</p>
|
|
<p>For an explanation of what this means and why it might be needed,
|
|
see <a href="S12Z-Register-Notation.html#S12Z-Register-Notation">S12Z Register Notation</a>.
|
|
</p>
|
|
|
|
</dd>
|
|
<dt>‘<samp>-mdollar-hex</samp>’</dt>
|
|
<dd><a name="index-_002dmdollar_002dhex-option_002c-dollar_002dhex"></a>
|
|
<a name="index-hexadecimal-prefix_002c-S12Z"></a>
|
|
<p>The ‘<samp>-mdollar-hex</samp>’ option affects the way that literal hexadecimal constants
|
|
are represented. When this option is specified, the assembler will consider
|
|
the ‘<samp>$</samp>’ character as the start of a hexadecimal integer constant. Without
|
|
this option, the standard value of ‘<samp>0x</samp>’ is expected.
|
|
</p>
|
|
<p>If you use this option, then you cannot have symbol names starting with ‘<samp>$</samp>’.
|
|
‘<samp>-mdollar-hex</samp>’ is implied if the ‘<samp>--traditional-format</samp>’
|
|
(see <a href="traditional_002dformat.html#traditional_002dformat">traditional-format</a>) is used.
