Hello,
the in-kernel floating point emulation seems seriously broken.
Running pkgsrc/benchmarks/paranoia on a mips system without FPU (userland
*not* compiled -msoft-float) gives:
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.

Even printf seems to have problems. I'm seeing e.g.:
What the machine gets for (Z + Z) / Z is 2.Dшяяяяяяяяяяяяяяe+00 .
anyone familiar with mips floating point ?
