<h4 class="subsection">9.24.9 Directives to control generation of MIPS ASE instructions</h4>

<p><a name="index-MIPS-MIPS_002d3D-instruction-generation-override-1284"></a><a name="index-g_t_0040code_007b_002eset-mips3d_007d-1285"></a><a name="index-g_t_0040code_007b_002eset-nomips3d_007d-1286"></a>The directive <code>.set mips3d</code> makes the assembler accept instructions
from the MIPS-3D Application Specific Extension from that point on
in the assembly.  The <code>.set nomips3d</code> directive prevents MIPS-3D
instructions from being accepted.

   <p><a name="index-SmartMIPS-instruction-generation-override-1287"></a><a name="index-g_t_0040code_007b_002eset-smartmips_007d-1288"></a><a name="index-g_t_0040code_007b_002eset-nosmartmips_007d-1289"></a>The directive <code>.set smartmips</code> makes the assembler accept
instructions from the SmartMIPS Application Specific Extension to the
MIPS32 <span class="sc">isa</span> from that point on in the assembly.  The
<code>.set nosmartmips</code> directive prevents SmartMIPS instructions from
being accepted.

   <p><a name="index-MIPS-MDMX-instruction-generation-override-1290"></a><a name="index-g_t_0040code_007b_002eset-mdmx_007d-1291"></a><a name="index-g_t_0040code_007b_002eset-nomdmx_007d-1292"></a>The directive <code>.set mdmx</code> makes the assembler accept instructions
from the MDMX Application Specific Extension from that point on
in the assembly.  The <code>.set nomdmx</code> directive prevents MDMX
instructions from being accepted.

   <p><a name="index-MIPS-DSP-Release-1-instruction-generation-override-1293"></a><a name="index-g_t_0040code_007b_002eset-dsp_007d-1294"></a><a name="index-g_t_0040code_007b_002eset-nodsp_007d-1295"></a>The directive <code>.set dsp</code> makes the assembler accept instructions
from the DSP Release 1 Application Specific Extension from that point
on in the assembly.  The <code>.set nodsp</code> directive prevents DSP
Release 1 instructions from being accepted.

   <p><a name="index-MIPS-DSP-Release-2-instruction-generation-override-1296"></a><a name="index-g_t_0040code_007b_002eset-dspr2_007d-1297"></a><a name="index-g_t_0040code_007b_002eset-nodspr2_007d-1298"></a>The directive <code>.set dspr2</code> makes the assembler accept instructions
from the DSP Release 2 Application Specific Extension from that point
on in the assembly.  This dirctive implies <code>.set dsp</code>.  The
<code>.set nodspr2</code> directive prevents DSP Release 2 instructions from
being accepted.

   <p><a name="index-MIPS-MT-instruction-generation-override-1299"></a><a name="index-g_t_0040code_007b_002eset-mt_007d-1300"></a><a name="index-g_t_0040code_007b_002eset-nomt_007d-1301"></a>The directive <code>.set mt</code> makes the assembler accept instructions
from the MT Application Specific Extension from that point on
in the assembly.  The <code>.set nomt</code> directive prevents MT
instructions from being accepted.

   <p><a name="index-MIPS-MCU-instruction-generation-override-1302"></a><a name="index-g_t_0040code_007b_002eset-mcu_007d-1303"></a><a name="index-g_t_0040code_007b_002eset-nomcu_007d-1304"></a>The directive <code>.set mcu</code> makes the assembler accept instructions
from the MCU Application Specific Extension from that point on
in the assembly.  The <code>.set nomcu</code> directive prevents MCU
instructions from being accepted.

   <p>Traditional <span class="sc">mips</span> assemblers do not support these directives.
