|
||
|
|
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-1520"></a><a name="index-g_t_0040code_007b_002eset-smartmips_007d-1521"></a><a name="index-g_t_0040code_007b_002eset-nosmartmips_007d-1522"></a>The directive <code>.set smartmips</code> makes the assembler accept
|
||
|
|
instructions from the SmartMIPS Application Specific Extension to the
|
||
|
|
MIPS32 ISA 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-1523"></a><a name="index-g_t_0040code_007b_002eset-mdmx_007d-1524"></a><a name="index-g_t_0040code_007b_002eset-nomdmx_007d-1525"></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-1526"></a><a name="index-g_t_0040code_007b_002eset-dsp_007d-1527"></a><a name="index-g_t_0040code_007b_002eset-nodsp_007d-1528"></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-1529"></a><a name="index-g_t_0040code_007b_002eset-dspr2_007d-1530"></a><a name="index-g_t_0040code_007b_002eset-nodspr2_007d-1531"></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 directive 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-1532"></a><a name="index-g_t_0040code_007b_002eset-mt_007d-1533"></a><a name="index-g_t_0040code_007b_002eset-nomt_007d-1534"></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-1535"></a><a name="index-g_t_0040code_007b_002eset-mcu_007d-1536"></a><a name="index-g_t_0040code_007b_002eset-nomcu_007d-1537"></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><a name="index-MIPS-SIMD-Architecture-instruction-generation-override-1538"></a><a name="index-g_t_0040code_007b_002eset-msa_007d-1539"></a><a name="index-g_t_0040code_007b_002eset-nomsa_007d-1540"></a>The directive <code>.set msa</code> makes the assembler accept instructions
|
||
|
|
from the MIPS SIMD Architecture Extension from that point on
|
||
|
|
in the assembly. The <code>.set nomsa</code> directive prevents MSA
|
||
|
|
instructions from being accepted.
|
||
|
|
|
||
|
|
<p><a name="index-Virtualization-instruction-generation-override-1541"></a><a name="index-g_t_0040code_007b_002eset-virt_007d-1542"></a><a name="index-g_t_0040code_007b_002eset-novirt_007d-1543"></a>The directive <code>.set virt</code> makes the assembler accept instructions
|
||
|
|
from the Virtualization Application Specific Extension from that point
|
||
|
|
on in the assembly. The <code>.set novirt</code> directive prevents Virtualization
|
||
|
|
instructions from being accepted.
|
||

|
<p><a name="index-MIPS-eXtended-Physical-Address-_0028XPA_0029-instruction-generation-override-1544"></a><a name="index-g_t_0040code_007b_002eset-xpa_007d-1545"></a><a name="index-g_t_0040code_007b_002eset-noxpa_007d-1546"></a>The directive <code>.set xpa</code> makes the assembler accept instructions
|
||
|
|
from the XPA Extension from that point on in the assembly. The
|
||
|
|
<code>.set noxpa</code> directive prevents XPA instructions from being accepted.
|
||
|
|
|
||
|
|
<p>Traditional MIPS assemblers do not support these directives.
