Hi,

I built qemu-system-ppc for OSX and Windows from
https://github.com/stsquad/qemu/tree/softfloat-refactor-and-fp16-v3
and noticed a considerable drop in floating point performance on both
hosts.
Running Mac OS 9.2 in OSX, using MacBench 3.0, the score for the
floating point performance dropped from ~60 to ~42.

Recent tcg optimisations had improved processor and floating point
performance considerably, but that gain seems to be more than lost for
the floating point performance.

Any idea what is causing this?

Best regards,
Howard
