<h4 class="subsection">9.27.6 Directives to control code generation</h4>
|

<p><a name="index-MIPS-directives-to-override-command-line-options-1500"></a><a name="index-g_t_0040code_007b_002emodule_007d-1501"></a>The <code>.module</code> directive allows command line options to be set directly
|
|
from assembly. The format of the directive matches the <code>.set</code>
|
|
directive but only those options which are relevant to a whole module are
|
|
supported. The effect of a <code>.module</code> directive is the same as the
|
|
corresponding command line option. Where <code>.set</code> directives support
|
|
returning to a default then the <code>.module</code> directives do not as they
|
|
define the defaults.
|
|
|
|
<p>These module-level directives must appear first in assembly.
|
|
|
|
<p>Traditional MIPS assemblers do not support this directive.

|
|
instruction encodings when generating code for the microMIPS processor.
|
|
This directive inhibits the use of any 16-bit instructions from that
|
|
point on in the assembly. The <code>.set noinsn32</code> directive allows
|
|
16-bit instructions to be accepted.
|
|
|
|
<p>Traditional MIPS assemblers do not support this directive.
