or act in loop-back mode for big-int division by a scalar,
or for a single scalar 128/64 div/mod.
+Again, just as with `sv.madded` and `sv.adde`, adventurous implementors
+may perform massively-wide DIV/MOD by transparently merging (fusing)
+the Vector element operations together, only inputting a single RC and
+outputting the last RC. Where efficient algorithms such as Goldschmidt
+are deployed internally this could dramatically reduce the cycle completion
+time for massive Vector DIV/MOD.

Just as with `divdeu` on which this instruction is based an overflow
detection is required. When the divisor is too small compared to
the dividend then the result may not fit into 64 bit. Knuth's
