From

First you need to generate the test cases. It looks like the current
ppc64.risu file is fairly complete, at least to some level. So:
mkdir ../risu-testcases-ppc64
./scripts/generate_all.sh ppc64.risu ../risu-testcases-ppc64
Then record traces from real hardware to compare against:
RISU=`pwd`/risu ./scripts/record_traces.sh ../risu-testcases-ppc64/*.bin
Now compare QEMU against hardware:
QEMU=qemu-ppc64 RISU=`pwd`/risu \
./scripts/run_risu ../risu-testcases-ppc64/*.bin
Which is all hunky dory until something fails. At which point it's a matter of
using qemu's -d and -dfilter options judiciously, and "objdump -b binary -m
ppc64 -D foo.bin".
