| <h4 class="subsection">9.24.1 S12Z Options</h4> |
| |
| <p><a name="index-options_002c-S12Z-1517"></a><a name="index-S12Z-options-1518"></a> |
| The S12Z version of <code>as</code> recognizes the following options: |
| |
| <dl> |
| <dt>‘<samp><span class="samp">-mreg-prefix=</span><var>prefix</var></samp>’<dd><a name="index-g_t_0040samp_007b_002dmreg_002dprefix_003d_0040var_007bprefix_007d_007d-option_002c-reg_002dprefix-1519"></a>You can use the ‘<samp><span class="samp">-mreg-prefix=</span><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>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>. |
| |
| <br><dt>‘<samp><span class="samp">-mdollar-hex</span></samp>’<dd><a name="index-g_t_0040samp_007b_002dmdollar_002dhex_007d-option_002c-dollar_002dhex-1520"></a><a name="index-hexadecimal-prefix_002c-S12Z-1521"></a>The ‘<samp><span class="samp">-mdollar-hex</span></samp>’ option affects the way that literal hexadecimal constants |
| are represented. When this option is specified, the assembler will consider |
| the ‘<samp><span class="samp">$</span></samp>’ character as the start of a hexadecimal integer constant. Without |
| this option, the standard value of ‘<samp><span class="samp">0x</span></samp>’ is expected. |
| |
| <p>If you use this option, then you cannot have symbol names starting with ‘<samp><span class="samp">$</span></samp>’. |
| ‘<samp><span class="samp">-mdollar-hex</span></samp>’ is implied if the ‘<samp><span class="samp">--traditional-format</span></samp>’ |
| (see <a href="traditional_002dformat.html#traditional_002dformat">traditional-format</a>) is used. |
