I think the #ifdef CONFIG_TCG_INTERPRETER sections belong before
the arch-specific sections. :-)

I will do this at some point if nobody beats me to it. :-)
BTW, I'm wondering about certain places that require host-specific
code... for example:
* qemu-lock.h, which is used by cpu_exec() for the tb lock and by
cpu_unlink_tb() for non-NPTL hosts.
* The generic cpu_get_real_ticks() doesn't seem great... I suppose
the MIPS version using clock() might be more appropriate?
Apart from this, I suppose user mode emulation simply has to depend
on host-specific code for signal handling... :-(
I gather INDEX_op_call handling could be improved? Presumably that's
really just a matter of casting to the right type of function pointer
when making each call?
Cheers,
