So you really want to do dynamic retranslation on ancient hardware? To
me emulated systems already feel slow on really recent machines, I
don't want to go back to something even slower.
If you use kqemu there even is near no performance hit at all, which I
believe is the main use of qemu on i386 anyway. Furthermore x86_64 is
_way_ faster, as it provides a lot more registers.
I think the benefit you get from cutting the gcc3 dependency is way more
important than a major performance hit that people will usually only see
on the next release of qemu, by which time things have shifted towards
x86_64 even more.
