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 dspr3 makes the assembler accept instructions
from the DSP Release 3 Application Specific Extension from that point
on in the assembly. This directive implies .set dsp and
.set dspr2. The .set nodspr3 directive prevents DSP
Release 3 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.
The directive .set mips16e2 makes the assembler accept instructions
from the MIPS16e2 Application Specific Extension from that point on in the
assembly, whenever in MIPS16 mode. The .set nomips16e2 directive
prevents MIPS16e2 instructions from being accepted, in MIPS16 mode. Neither
directive affects the state of MIPS16 mode being active itself which has
separate controls.
The directive .set crc makes the assembler accept instructions
from the CRC Extension from that point on in the assembly. The
.set nocrc directive prevents CRC instructions from being accepted.
The directive .set ginv makes the assembler accept instructions
from the GINV Extension from that point on in the assembly. The
.set noginv directive prevents GINV instructions from being accepted.
The directive .set loongson-mmi makes the assembler accept
instructions from the MMI Extension from that point on in the assembly.
The .set noloongson-mmi directive prevents MMI instructions from
being accepted.
The directive .set loongson-cam makes the assembler accept
instructions from the Loongson CAM from that point on in the assembly.
The .set noloongson-cam directive prevents Loongson CAM instructions
from being accepted.
The directive .set loongson-ext makes the assembler accept
instructions from the Loongson EXT from that point on in the assembly.
The .set noloongson-ext directive prevents Loongson EXT instructions
from being accepted.
The directive .set loongson-ext2 makes the assembler accept
instructions from the Loongson EXT2 from that point on in the assembly.
This directive implies .set loognson-ext.
The .set noloongson-ext2 directive prevents Loongson EXT2 instructions
from being accepted.
Traditional MIPS assemblers do not support these directives.
