Hi,
USE_CODE_COPY is only used for user level emulation. My current plan is
to remove this code ASAP because it adds too much complexity to QEMU and
has little use.
IMHO it is more useful to concentrate on making the x86 target more
accurate (e.g. FPU support in SOFT_FLOAT mode, full segment checks, SMI
mode) while being totally independent of the x86 host.
The case where performance is needed can be handled more efficiently by
using kqemu or qvm86.
Regards,
Fabrice.

Hi all.
I was looking at the qemu dynamic rewriting code for system emulation
(and NOT running user level processes). Is direct copying
(USE_CODE_COPY) ever used? It looks to me that it's not, since the
softmmu is always used...
I am mostly interested in the X86_64 target.
thanks,
