For what test case? This should not have been on any hot path.
I tested Mac OS 9.2 and 10.3/4 with qemu-system-ppc built from 4.2 and current master like this:
./qemu-system-ppc -L pc-bios -boot c -M mac99,via=pmu -m 512 \
-serial stdio -sdl \
-hda 9.2.img (10.3.img|10.4.img)
Mac OS 9.2 MacBench 5.0 reports processor speed:
