These instructions have wide dests so they should use ARITH_WIDE_DEST
.

These should use the ARITH_MAC
which adds the destination of each uop as a source.
@orion160 the uop generators for the vector floating point instructions need to be reviewed. I would also add a new execution unit for |
@kathlenemagnus-mips should it be the same with vfdiv? I think that the float division, and the reciprocal estimates could make use of this resource. |
