Thanks. I thought about that first as well, but can't. The information
if an intercept should occur is defined in the VMCB, which is passed as
argument on VMRUN (so whenever one enters the VM). This means that the
very same TB can be executed with completely different intercepts, which
means I have to fall back to runtime detection in op.c.
I thought about moving some functionality from helper.c to op.c.
Does that improve anything?
