|
||
|
|
|
||
|
|
<p>These ‘<samp><span class="samp">-m</span></samp>’ options are defined for the H8/300 implementations:
|
||
|
|
|
||
|
|
<dl>
|
||
|
|
<dt><code>-mrelax</code><dd><a name="index-mrelax-1690"></a>Shorten some address references at link time, when possible; uses the
|
||
|
|
linker option <samp><span class="option">-relax</span></samp>. See <a href="../ld/H8_002f300.html#H8_002f300"><code>ld</code> and the H8/300</a>, for a fuller description.
|
||
|
|
|
||
|
|
<br><dt><code>-mh</code><dd><a name="index-mh-1691"></a>Generate code for the H8/300H.
|
||
|
|
|
||
|
|
<br><dt><code>-ms</code><dd><a name="index-ms-1692"></a>Generate code for the H8S.
|
||
|
|
|
||
|
|
<br><dt><code>-mn</code><dd><a name="index-mn-1693"></a>Generate code for the H8S and H8/300H in the normal mode. This switch
|
||
|
|
must be used either with <samp><span class="option">-mh</span></samp> or <samp><span class="option">-ms</span></samp>.
|
||
|
|
|
||
|
|
<br><dt><code>-ms2600</code><dd><a name="index-ms2600-1694"></a>Generate code for the H8S/2600. This switch must be used with <samp><span class="option">-ms</span></samp>.
|
||
|
|
|
||
|
|
<br><dt><code>-mexr</code><dd><a name="index-mexr-1695"></a>Extended registers are stored on stack before execution of function
|
||
|
|
with monitor attribute. Default option is <samp><span class="option">-mexr</span></samp>.
|
||
|
|
This option is valid only for H8S targets.
|
||
|
|
|
||
|
|
<br><dt><code>-mno-exr</code><dd><a name="index-mno_002dexr-1696"></a>Extended registers are not stored on stack before execution of function
|
||
|
|
with monitor attribute. Default option is <samp><span class="option">-mno-exr</span></samp>.
|
||
|
|
This option is valid only for H8S targets.
|
||
|
|
|
||
|
|
<br><dt><code>-mint32</code><dd><a name="index-mint32-1697"></a>Make <code>int</code> data 32 bits by default.
|
||
|
|
|
||
|
|
<br><dt><code>-malign-300</code><dd><a name="index-malign_002d300-1698"></a>On the H8/300H and H8S, use the same alignment rules as for the H8/300.
|
||
|
|
The default for the H8/300H and H8S is to align longs and floats on
|
||
|
|
4-byte boundaries.
|
||
|
|
<samp><span class="option">-malign-300</span></samp> causes them to be aligned on 2-byte boundaries.
|
||
|
|
This option has no effect on the H8/300.
