I don't quite understand, I think here 8x8 because zve64x is not suitable
for sharing, it shares between dc16x16 and dc32x32, there isn't much common
code, it would require adding 3 if-else statements and function parameters,
it feels okay not to extract too.

Did you try to share the common code after getdc and see how slower it is? If
an extra static branch has negligible overhead, it would reduce binary size

Thanks , I didn't know that before

Okay, reduced if/else in the response.

You would need a lot fewer if/else if you passed the order/bit-width instead
of the size as macro parameter.
Similarly, this can be folded as a single .else:
+.elseif \type == 127
+li t1, 127
+.elseif \type
