The directive .set mips3d makes the assembler accept instructions
from the MIPS-3D Application Specific Extension from that point on
in the assembly. The .set nomips3d directive prevents MIPS-3D
instructions from being accepted.
The directive .set smartmips makes the assembler accept
instructions from the SmartMIPS Application Specific Extension to the
MIPS32 ISA from that point on in the assembly. The
.set nosmartmips directive prevents SmartMIPS instructions from
being accepted.
The directive .set mdmx makes the assembler accept instructions
from the MDMX Application Specific Extension from that point on
in the assembly. The .set nomdmx directive prevents MDMX
instructions from being accepted.
The directive .set dsp makes the assembler accept instructions
from the DSP Release 1 Application Specific Extension from that point
on in the assembly. The .set nodsp directive prevents DSP
Release 1 instructions from being accepted.
The directive .set dspr2 makes the assembler accept instructions
from the DSP Release 2 Application Specific Extension from that point
on in the assembly. This directive implies .set dsp. The
.set nodspr2 directive prevents DSP Release 2 instructions from
being accepted.
The directive .set mt makes the assembler accept instructions
from the MT Application Specific Extension from that point on
in the assembly. The .set nomt directive prevents MT
instructions from being accepted.
The directive .set mcu makes the assembler accept instructions
from the MCU Application Specific Extension from that point on
in the assembly. The .set nomcu directive prevents MCU
instructions from being accepted.
The directive .set msa makes the assembler accept instructions
from the MIPS SIMD Architecture Extension from that point on
in the assembly. The .set nomsa directive prevents MSA
instructions from being accepted.
The directive .set virt makes the assembler accept instructions
from the Virtualization Application Specific Extension from that point
on in the assembly. The .set novirt directive prevents Virtualization
instructions from being accepted.
The directive .set xpa makes the assembler accept instructions
from the XPA Extension from that point on in the assembly. The
.set noxpa directive prevents XPA instructions from being accepted.
Traditional MIPS assemblers do not support these directives.
