Works great!

so im doing some benchmarks to see any general diference.
i trying PCMark 2002, any other sugestion?
I think the benchmark programs is a good choice to test virtual CPU, becouse
they use a lot of optimized intructions.

Well, when i use -mregpar=x, que qemu made a lot of 'booboos'. Some time start,
others guest Win98 and Linux crash...
not recomended for "production" hehe :P

Im looking for

I'll try to workarround compilation problem, doing it by hand,
it happens only with help.c (well, all help.c in qemu tree)

enter in i386 , i386-softemu , ppc-softemu
and doing:

gcc -Wall -O2 -march=pentium -fno-strict-aliasing -fomit-frame-pointer -I. -I/root/qemu-0.6.0/target-i386 -I/root/qemu-0.6.0 -D_GNU_SOURCE -I/root/qemu-0.6.0/slirp -c -o helper.o /root/qemu-0.6.0/target-i386/helper.c

just  return to root tree compilation and do make again to continue.

I will see what instable qemu will be with -regparm=[1..3].  :)
