|
|
from the MIPS-3D Application Specific Extension from that point on
|
||
|

<p>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
