9.27.12 Directives to control generation of MIPS ASE instructions

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.
