| 72 | <a name="index-MIPS-directives-to-override-command-line-options"></a> |
| 73 | <a name="index-_002emodule"></a> |
| 74 | <p>The <code>.module</code> directive allows command line options to be set directly |
| 75 | from assembly. The format of the directive matches the <code>.set</code> |
| 76 | directive but only those options which are relevant to a whole module are |
| 77 | supported. The effect of a <code>.module</code> directive is the same as the |
| 78 | corresponding command line option. Where <code>.set</code> directives support |
| 79 | returning to a default then the <code>.module</code> directives do not as they |
| 80 | define the defaults. |
| 81 | </p> |
| 82 | <p>These module-level directives must appear first in assembly. |
| 83 | </p> |
| 84 | <p>Traditional MIPS assemblers do not support this directive. |
| 85 | </p> |
| 86 | <a name="index-MIPS-32_002dbit-microMIPS-instruction-generation-override"></a> |
| 87 | <a name="index-_002eset-insn32"></a> |
| 88 | <a name="index-_002eset-noinsn32"></a> |
| 89 | <p>The directive <code>.set insn32</code> makes the assembler only use 32-bit |
| 90 | instruction encodings when generating code for the microMIPS processor. |
| 91 | This directive inhibits the use of any 16-bit instructions from that |
| 92 | point on in the assembly. The <code>.set noinsn32</code> directive allows |
| 93 | 16-bit instructions to be accepted. |
| 94 | </p> |
| 95 | <p>Traditional MIPS assemblers do not support this directive. |
