thanks, this is a good starting point. MIPS floating point emulation
is definitively brocken:
The number of FAILUREs encountered = 3.
The number of SERIOUS DEFECTs discovered = 1.
The number of DEFECTs discovered = 4.
The number of FLAWs discovered = 2.
There is also issues with floating point printing, e.g.
What the machine gets for (Z + Z) / Z is 2.Døÿÿÿÿÿÿÿÿÿÿÿÿÿÿe+00 .
this needs to be investigated, but I know ~nothing about
floating point arithmetic, I'll need to find some documentation
about this before doing any serious work.
