#### 9.27.11 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 dirctive 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 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.

Traditional MIPS assemblers do not support these directives.
