I think you're both saying the same thing here. During OpCode
generation, no run-time information of a particular code path is
available, only what can be logically deduced from the source code
itself - and that's exactly what static analysis means.
I imagine the reason static analysers are generally run as a separate
step rather than just before execution is because then you _really_
don't care about performance, and it's more convenient to get the
results on demand, rather than them appearing in your server logs.
