| |
| <p><a name="index-MN10300-options-1696"></a> |
| These <samp><span class="option">-m</span></samp> options are defined for Matsushita MN10300 architectures: |
| |
| <dl> |
| <dt><code>-mmult-bug</code><dd><a name="index-mmult_002dbug-1697"></a>Generate code to avoid bugs in the multiply instructions for the MN10300 |
| processors. This is the default. |
| |
| <br><dt><code>-mno-mult-bug</code><dd><a name="index-mno_002dmult_002dbug-1698"></a>Do not generate code to avoid bugs in the multiply instructions for the |
| MN10300 processors. |
| |
| <br><dt><code>-mam33</code><dd><a name="index-mam33-1699"></a>Generate code which uses features specific to the AM33 processor. |
| |
| <br><dt><code>-mno-am33</code><dd><a name="index-mno_002dam33-1700"></a>Do not generate code which uses features specific to the AM33 processor. This |
| is the default. |
| |
| <br><dt><code>-mreturn-pointer-on-d0</code><dd><a name="index-mreturn_002dpointer_002don_002dd0-1701"></a>When generating a function which returns a pointer, return the pointer |
| in both <code>a0</code> and <code>d0</code>. Otherwise, the pointer is returned |
| only in a0, and attempts to call such functions without a prototype |
| would result in errors. Note that this option is on by default; use |
| <samp><span class="option">-mno-return-pointer-on-d0</span></samp> to disable it. |
| |
| <br><dt><code>-mno-crt0</code><dd><a name="index-mno_002dcrt0-1702"></a>Do not link in the C run-time initialization object file. |
| |
| <br><dt><code>-mrelax</code><dd><a name="index-mrelax-1703"></a>Indicate to the linker that it should perform a relaxation optimization pass |
| to shorten branches, calls and absolute memory addresses. This option only |
| has an effect when used on the command line for the final link step. |
| |
| <p>This option makes symbolic debugging impossible. |
